Fastests way to empty a dictionary into an Excel sheet - vba

What is the fastest way to empty a Scripting.Dictionary into an excel sheet? This is what I'm doing right now, but for a dictionary with about 3000 elements, it's noticeably slow. I've made every optimization I can think of.
Here's a bare-bones version of what I have:
'wordCount and emailCount are late bound "Scripting.Dictionary" objects
Private Sub DictionaryToExcel(ByRef wordCount As Object, emailCount As Object)
oExcel.EnableEvents = False
oExcel.ScreenUpdating = False
Set oWorkbook = oExcel.Workbooks.Add
oExcel.Calculation = -4135
With oWorkbook.Sheets(1)
iRow = 1
For Each strKey In wordCount.Keys()
iWordCount = wordCount.Item(strKey)
iEmailCount = emailCount.Item(strKey)
If iWordCount > 2 And iEmailCount > 1 Then
.Cells(iRow, 1) = strKey
.Cells(iRow, 2) = iEmailCount
.Cells(iRow, 3) = iWordCount
iRow = iRow + 1
End If
Next strKey
End With
oExcel.ScreenUpdating = True
End Sub
Here's the full version including every action I'm taking (mostly formatting, but with one relatively expensive action of doing a spell check on the strKey (Although I think this is already optimized as much as it can be:
'wordCount and emailCount are late bound "Scripting.Dictionary" objects
Private Sub DictionaryToExcel(ByRef wordCount As Object, emailCount As Object)
Dim oExcel As Object, oWorkbook As Object
Dim strKey As Variant, iRow As Long
Dim iWordCount As Long, iEmailCount As Long, spellCheck As Boolean
Set oExcel = CreateObject("Excel.Application")
oExcel.EnableEvents = False
oExcel.ScreenUpdating = False
Set oWorkbook = oExcel.Workbooks.Add
oExcel.Calculation = -4135
With oWorkbook.Sheets(1)
iRow = 1
.Columns(1).NumberFormat = "#"
For Each strKey In wordCount.Keys()
iWordCount = wordCount.Item(strKey)
iEmailCount = emailCount.Item(strKey)
spellCheck = False
If iWordCount > 2 And iEmailCount > 1 Then
.Cells(iRow, 1) = strKey
.Cells(iRow, 2) = iEmailCount
.Cells(iRow, 3) = iWordCount
spellCheck = oExcel.CheckSpelling(strKey)
If Not spellCheck Then spellCheck = oExcel.CheckSpelling(StrConv(strKey, vbProperCase))
.Cells(iRow, 4) = IIf(spellCheck, "Yes", "No")
iRow = iRow + 1
End If
Next strKey
.Sort.SortFields.Clear
.Sort.SortFields.Add Key:=.Columns(4), Order:=1
.Sort.SortFields.Add Key:=.Columns(2), Order:=2
.Sort.SortFields.Add Key:=.Columns(3), Order:=2
.Sort.SetRange .Range(.Columns(1), .Columns(4))
.Sort.Apply
.Rows(1).Insert
.Rows(1).Font.Bold = True
.Cells(1, 1) = "Word"
.Cells(1, 2) = "Emails Containing"
.Cells(1, 3) = "Total Occurrences"
.Cells(1, 4) = "Is a common word?"
.Range(.Columns(1), .Columns(4)).AutoFit
If .Columns(1).ColumnWidth > 20 Then .Columns(1).ColumnWidth = 20
.Range(.Columns(2), .Columns(4)).HorizontalAlignment = -4152
End With
oExcel.Visible = True
oExcel.ScreenUpdating = True
End Sub
I know there's a really fast method to fire a 2D array into a range of cells, but I'm not sure if there's something similar for Dictionaries.
*edit*
So far, I've made an improvement by adding the values to an array instead of directly to excel cells, and then firing the array to excel:
Private Sub DictionaryToExcel(ByRef wordCount As Object, emailCount As Object)
Dim arrPaste() As Variant
Set oWorkbook = oExcel.Workbooks.Add
iRow = 1: total = wordCount.count
ReDim arrPaste(1 To total, 1 To 4)
For Each strKey In wordCount.Keys()
iWordCount = wordCount.Item(strKey)
iEmailCount = emailCount.Item(strKey)
spellCheck = False
If iWordCount > 2 And iEmailCount > 1 Then
arrPaste(iRow, 1) = strKey
arrPaste(iRow, 2) = iEmailCount
arrPaste(iRow, 3) = iWordCount
iRow = iRow + 1
End If
count = count + 1
Next strKey
With oWorkbook.Sheets(1)
.Range(.Cells(1, 1), .Cells(total, 4)) = arrPaste

Try converting the Dictionaries to Array(s) and then transferring the Array(s) to the Worksheet. The conversion should be relatively quick since it is all in memory.
Then, you should be able to write the array to the worksheet in one action, rather than inside a loop.

Speed Up Macro Extracting Rows from Data using Column to Match

I'm looking for a way to speed up this code as it takes my computer 20-30 minutes to run. It essentially runs through a list of column values in sheet "A" and if It matches a column value in sheet "B" it will pull the entire corresponding row to the sheet "Match".
Sub MatchSheets()
Dim lastRowAF As Integer
Dim lastRowL As Integer
Dim lastRowM As Integer
Dim foundTrue As Boolean
Application.ScreenUpdating = False
lastRowAF = Sheets("FHA").Cells(Sheets("FHA").Rows.Count, "AF").End(xlUp).Row
lastRowL = Sheets("New Construction").Cells(Sheets("New Construction").Rows.Count, "L").End(xlUp).Row
lastRowM = Sheets("Match").Cells(Sheets("Match").Rows.Count, "A").End(xlUp).Row
For i = 1 To lastRowAF
foundTrue = False
For j = 1 To lastRowL
If Sheets("FHA").Cells(i, 32).Value = Sheets("New Construction").Cells(j, 12).Value Then
foundTrue = True
Exit For
End If
Next j
If foundTrue Then
Sheets("FHA").Rows(i).Copy Destination:= _
Sheets("Match").Rows(lastRowM + 1)
lastRowM = lastRowM + 1
End If
Next i
Application.ScreenUpdating = True
End Sub
Collections are optimized for looking values. Using a combination of a Collection and Array is usually the best way to match two list. 20K Rows X 54 Columns (140K Values) took this code 10.87 seconds to copy over on a slow PC.
Sub NewMatchSheets()
Dim t As Double: t = Timer
Const NUM_FHA_COLUMNS As Long = 54, AF As Long = 32
Dim list As Object
Dim key As Variant, data() As Variant, results() As Variant
Dim c As Long, r As Long, count As Long
ReDim results(1 To 50000, 1 To 100)
Set list = CreateObject("System.Collections.ArrayList")
With ThisWorkbook.Worksheets("New Construction")
data = .Range("L1", .Cells(.Rows.count, "L").End(xlUp)).Value
For Each key In data
If key <> "" Then
If Not list.Contains(key) Then list.Add key
End If
Next
End With
With ThisWorkbook.Worksheets("FHA")
data = .Range(.Range("A1").Resize(1, NUM_FHA_COLUMNS), .Cells(.Rows.count, AF).End(xlUp)).Value
For r = 1 To UBound(data)
key = data(r, AF)
If list.Contains(key) Then
count = count + 1
For c = 1 To UBound(data, 2)
results(count, c) = data(r, c)
Next
End If
Next
End With
If count = 0 Then Exit Sub
Application.Calculation = xlCalculationManual
Application.ScreenUpdating = True
With ThisWorkbook.Worksheets("Match")

use variant arrays:

Dim FHAArr As Variant
FHAArr = Sheets("FHA").Range(Sheets("FHA").Cells(1, 1), Sheets("FHA").Cells(lastRowAF, Columns.Count).End(xlToLeft)).Value
Dim NewConArr As Variant
NewConArr = Sheets("New Construction").Range(Sheets("New Construction").Cells(1, 12), Sheets("New Construction").Cells(lastRowL, 12)).Value

Get rid of all the nested loop and work with arrays.
Your narrative seemed to suggest that there might be multiple matches for any one value but your code only looks for a single match then Exit For. I'll work with the latter of the two scenarios.
Sub MatchSheets()
Dim i As Long, j As Long
Dim vFM As Variant, vNC As Variant
Debug.Print Timer
With Worksheets("New Construction")
vNC = .Range(.Cells(1, "L"), _
.Cells(.Rows.Count, "L").End(xlUp)).Value2
End With
With Worksheets("FHA")
vFM = .Range(.Cells(1, "A"), _
.Cells(.Rows.Count, _
.Cells(1, .Columns.Count).End(xlToLeft).Column).End(xlUp)).Value2
End With
ReDim vM(LBound(vFM, 2) To UBound(vFM, 2), 1 To 1)
For i = LBound(vFM, 1) To UBound(vFM, 1)
If Not IsError(Application.Match(vFM(i, 32), vNC, 0)) Then
For j = LBound(vFM, 2) To UBound(vFM, 2)
vM(j, UBound(vM, 2)) = vFM(i, j)
Next j
ReDim Preserve vM(LBound(vFM, 2) To UBound(vFM, 2), LBound(vM, 2) To UBound(vM, 2) + 1)
End If
Next i
With Worksheets("match")
.Cells(.Rows.Count, "A").End(xlUp).Offset(1, 0).Resize(UBound(vM, 2), UBound(vM, 1)) = _
Application.Transpose(vM)
End With
Application.ScreenUpdating = True
Debug.Print Timer
End Sub
Try changing this line:
Sheets("FHA").Rows(i).Copy Destination:= _
Sheets("Match").Rows(lastRowM + 1)
For the following line:
Sheets("Match").Rows(lastRowM + 1).Value for Sheets("FHA").Rows(i).value
If you really need to shave milliseconds, you could also set: lastRowM to be:
lastRowM = Sheets("Match").Cells(Sheets("Match").Rows.Count, "A").End(xlUp).Row + 1
And use:
Sheets("Match").Rows(lastRowM).Value for Sheets("FHA").Rows(i).value
Thus saving you an addition every time you go through that part of the code

Speed Up Matching program in Excel VBA

I am writing a VBA code on excel using loops to go through 10000+ lines.
Here is an example of the table
And here is the code I wrote :
Sub Find_Matches()
Dim wb As Workbook
Dim xrow As Long
Set wb = ActiveWorkbook
wb.Worksheets("Data").Activate
tCnt = Sheets("Data").UsedRange.Rows.Count
Dim e, f, a, j, h As Range
xrow = 2
Application.ScreenUpdating = False
Application.Calculation = xlManual
For xrow = 2 To tCnt Step 1
Set e = Range("E" & xrow)
Set f = e.Offset(0, 1)
Set a = e.Offset(0, -4)
Set j = e.Offset(0, 5)
Set h = e.Offset(0, 3)
For Each Cell In Range("E2:E" & tCnt)
If Cell.Value = e.Value Then
If Cell.Offset(0, 1).Value = f.Value Then
If Cell.Offset(0, -4).Value = a.Value Then
If Cell.Offset(0, 5).Value = j.Value Then
If Cell.Offset(0, 3).Value = h.Value Then
If (e.Offset(0, 7).Value) + (Cell.Offset(0, 7).Value) = 0 Then
Cell.EntireRow.Interior.Color = vbYellow
e.EntireRow.Interior.Color = vbYellow
End If
End If
End If
End If
End If
End If
Next
Next
End Sub
As you can imagine, this is taking a lot of time to go through 10000+ lines and I would like to find a faster solution. There must be a method I don't think to avoid the over looping
Here are the condition :
For each line, if another line anywhere in the file has the exact same
:
Buyer ID (col. E)
`# purchased (col. F)
Product ID (col.A)
Payment (col. J)
Date purchased (col. H)
Then, if the SUM of the Amount (col. L) the those two matching line is
0, then color both rows in yellow.
Note that extra columns are present and not being compared (eg- col. B) but are still important for the document and cannot be deleted to ease the process.
Running the previous code, in my example, row 2 & 5 get highlighted :
This is using nested dictionaries and arrays to check all conditions

I suggest a different approach altogether: add a temporary column to your data that contains a concatenation of each cell in the row. This way, you have:
A|B|C|D|E
1|Mr. Smith|500|A|1Mr. Smith500A
Then use Excel's conditional formatting on the temporary column, highlighting duplicate values. There you have your duplicated rows. Now it's only a matter of using a filter to check which ones have amounts equal to zero.
You can use the CONCATENATE function; it requires you to specify each cell separately and you can't use a range, but in your case (comparing only some of the columns) it seems like a good fit.
Maciej's answer is easy to implement (if you can add columns to your data without interrupting anything), and I would recommend it if possible.
However, for the sake of answering your question, I will contribute a VBA solution as well. I tested it on dataset that is a bit smaller than yours, but I think it will work for you. Note that you might have to tweak it a little (which row you start on, table name, etc) to fit your workbook.
Most notably, the segment commented with "Helper column" is something you most likely will have to adjust - currently, it compares every cell between A and H for the current row, which is something you may or may not want.
I've tried to include a little commentary in the code, but it's not much. The primary change is that I'm using in-memory processing of an array rather than iterating over a worksheet range (which for larger datasets should be exponentially faster).
Option Base 1
Option Explicit
' Uses ref Microsoft Scripting Runtime
Sub Find_Matches()
Dim wb As Workbook, ws As Worksheet
Dim xrow As Long, tCnt As Long
Dim e As Range, f As Range, a As Range, j As Range, h As Range

Dim arrSize As Long, i As Long, k As Long
Dim c As Variant
Set wb = ThisWorkbook
Set ws = wb.Worksheets("Data")
ws.Activate
tCnt = ws.UsedRange.Rows.Count
xrow = 2
Application.ScreenUpdating = False
Application.Calculation = xlManual
' Read range into an array so we process in-memory
sheetArr = ws.Range("A2:H" & tCnt)
arrSize = UBound(sheetArr, 1)
' Build new arr with "helper column"
ReDim arr(1 To arrSize, 1 To 9)
For i = 1 To arrSize
For k = 1 To 8
arr(i, k) = sheetArr(i, k)
arr(i, 9) = CStr(arr(i, 9)) & CStr(arr(i, k)) ' "Helper column"

For i = LBound(arr, 1) To UBound(arr, 1)
If Not colorTheseYellow.Exists(i) Then colorResults = Split(ReturnLines(arr(i, 9), arr), ";")
For Each c In colorResults
If Not colorTheseYellow.Exists(CLng(c)) Then colorTheseYellow.Add CLng(c), CLng(c)
Next c

' Enact row colors
For Each dictItem In colorTheseYellow
'Debug.Print "dict: "; dictItem
If dictItem <> 0 Then ws.ListObjects(1).ListRows(CLng(dictItem)).Range.Interior.Color = vbYellow
Next dictItem
End Sub
Function ReturnLines(ByVal s As String, ByRef arr() As Variant) As String
' Returns a "Index;Index" string indicating the index/indices where the second, third, etc. instance(s) of s was found
' Returns "0;0" if 1 or fewer matches
Dim i As Long
Dim j As Long
Dim tmp As String
ReturnLines = 0

tmp = "0"
'Debug.Print "arg: " & s
For i = LBound(arr, 1) To UBound(arr, 1)
If arr(i, 9) = s Then

'Debug.Print "arr: " & arr(i, 9)
'Debug.Print "ReturnLine: " & i

On my simple dataset, it yields this result (marked excellently with freehand-drawn color indicators):
Thanks everybody for your answers,
Paul Bica's solution actually worked and I am using a version of this code now.
But, just to animate the debate, I think I also found another way around my first code, inspired by Maciej's idea of concatenating the cells and using CStr to compare the values and, of course Vegard's in-memory processing by using arrays instead of going through the workbook :
Sub Find_MatchesStr()
Dim AmountArr(300) As Variant
Dim rowArr(300) As Variant
Dim ws As Worksheet
Dim wb As Workbook
Set ws = ThisWorkbook.Sheets("Data")
ws.Activate
Range("A1").Select

For i = 2 To rCnt
If i = rCnt Then
Exit For
Else
intCnt = 0
strA = ws.Cells(i, 1).Value
strE = ws.Cells(i, 5).Value
strF = ws.Cells(i, 6).Value
strH = ws.Cells(i, 8).Value
strL = ws.Cells(i, 10).Value
For j = i To rCnt - 1
strSearchA = ws.Cells(j, 1).Value
strSearchE = ws.Cells(j, 5).Value
strSearchF = ws.Cells(j, 6).Value
strSearchH = ws.Cells(j, 8).Value
strSearchL = ws.Cells(j, 10).Value
If CStr(strE) = CStr(strSearchE) And CStr(strA) = CStr(strSearchA) And CStr(strF) = CStr(strSearchF) And CStr(strH) = CStr(strSearchH) And CStr(strL) = CStr(strSearchL) Then
AmountArr(k) = ws.Cells(j, 12).Value
rowArr(k) = j
intCnt = intCnt + 1
k = k + 1

Exit For
End If
Next

Exit For
End If
Next
If intCnt = 1 Then
Else
If strSum = 0 Then

Next
End If
End If
i = i + (intCnt - 1)
k = 0
Erase AmountArr
Erase rowArr
End If
Next
Range("A1").Select
End Sub
I still have some mistakes (rows not higlighted when they should be), the above code is not perfect, but I thought it'd be OK to give you an idea of where I was going before Paul Bica's solution came in.
Thanks again !

Improvement on 3 Criteria Vlookup macro

I have a list with 3 variables in the sheet "Combined" in columns A; B; C.
The workbook contains 98 sheets, with those 3 variables still in A; B; C columns but in different combinations and with a fourth column which never repeats itself, as the sheets go on, which i need to bring in the "Combined" sheet, always adding another column for the next sheet I vlookup. : A B C + D(from the next sheet) + E(from the next sheet) and so on.
I have a UDF that Vlookups on 3 based on 3 criterias and a macro that cycles through the sheets and bring the values where i want them. The problem is, it's pretty slow, left it from yesterday and its on sheet 60. Any suggestions on improving it would greatly help, Thank you in advance!

Use Arrays to speed it up, my friend! Load all your sheets (or just the current sheet in the loop) into an array in VBA's memory and do the .CountIf and .Find on arrayVar(row) instead of Table_Range.Columns(1).
You will be really surprised how much quicker it goes. Do it!
Here's a tutorial I like on arrays...
http://www.cpearson.com/excel/ArraysAndRanges.aspx
Here's a guy who speed-tested an application like yours...
https://fastexcel.wordpress.com/2011/10/26/match-vs-find-vs-variant-array-vba-performance-shootout/
The basics is like this:
Sub Play_With_Arrays()
Dim varArray() As Variant
Dim lngArray() As Long
ReDim varArray(1 To 1000)
ReDim lngArray(1 To 1000)
For A = 1 To 1000
lngArray(A) = A / 2
varArray(A) = A / 2 & " examples"
Next
searchterm = 345
For B = 1 To 1000
If lngArray(B) = searchterm Then
FoundRow = B
End If
Next
searchterm2 = "5 ex"
FoundStrRowCount = 0
For C = 1 To 1000
If InStr(1, varArray(C), searchterm2, vbBinaryCompare) Then
FoundStrRowCount = FoundStrRowCount + 1
End If
Next
MsgBox (FoundRow & " in long array and " & FoundStrRowCount & " in var array")
End Sub
Something like this should be much faster:
Public Function ThreeVLookup(ByVal arg_Col1LookupVal As Variant, _
ByVal arg_Col2LookupVal As Variant, _
ByVal arg_Col3LookupVal As Variant, _
ByVal arg_LookupTable As Range, _

Issue with row combining macro deleting data

I have a spreadsheet of data that looks something like this:
V1 Wht
V1 blck
V1 Red
V2 Wht
V2 Grn
V3 prpl
and I need it to simplify down to
V1 wht, blck, red
V2 Wht, grn
V3 prpl
I found a Macro online that will do this

However it only works for small chunks of around 40 values or less. Anything more and the sub will paste the values for the keys in left column, however, the right column where the items should be, will be blank.
Is there any way to modify this code to be able to handle more data safely?
Thanks!
Tranpose has a limit of 255 chars length. Anyhow in your code you dont need to transpose the data at all. Drop the transpose part and it works fine.
Edit: You do need to transpose the keys and values. There is a workaround for the limit. I have added that. Code copied from :https://stackoverflow.com/a/35399740/3961708

Compare Ranges to see if they are equal

I am working on my computer to automate a quote in Excel with VBA
It consists of finding duplicates so they can be summed.
For example:
I have the following information:
Click here for the Excel file
The range from A2:C4 is a group that it states there are 28 bolts, 1 nut for each bolt & 1 washer for each bolt.
A5:C7 is another group that is the same 28 bolts, 1 nut for each bolt & 1 washer for each bolt.
A11:C13 is another group but the difference is that for this one are 2 nuts & 2 washer per bolt.
So this wont be sum
This would be the result:
I have the following code where it only looks through all the cells, I can't find a way to make it look in groups or ranges.

Here is an approach that utilizes User Defined Object for the Hardware, and Hardware groups.
We could create more compact code with fewer loops, but, unless there is a significant speed issue, this is probably more readable, and can be more easily adapted to future needs.
We create two class modules (and be sure to rename them as indicated in the code).
One class module is for the hardware items, the second is for the different groups.
The hardware items properties are the description, the weight per item, and the number of items.
The hardware groups properties are a collection of Hardware items, and the Quantity of items in that group.
We then combine the hardware groups into a collection of unique hardware groups.
As the code is written, you could combine in other ways to generate other types of reports.
The results:
Class Module 1
'**Rename: cHardware**
Option Explicit
Private pDescription As String
Private pWt As Double
Private pItemCount As Long
Public Property Get Description() As String
Description = pDescription
End Property
Public Property Let Description(Value As String)
pDescription = Value
End Property
Public Property Get Wt() As Double
Wt = pWt
End Property
Public Property Let Wt(Value As Double)
pWt = Value
End Property
Public Property Get ItemCount() As Long
ItemCount = pItemCount
End Property
Public Property Let ItemCount(Value As Long)
pItemCount = Value
End Property
Class Module 2
'**Rename: cHardwareGrp**
Option Explicit
Private pHW As cHardWare
Private pHWs As Collection
Private pQty As Long
Private Sub Class_Initialize()
Set pHWs = New Collection

Public Property Get HW() As cHardWare

Hmmm. I see from your comments that the hardware may not always be in the same order. I will add a sorting routine to our group generation so that will be irrelevant.
EDIT: The AddHW function was modified to insert the HW items in sorted order. Since there should only be a few items, this insertion sort should be adequate.
Taking a different approach.
take advantage of the structure; three lines define it
Put results on a different tab
