Creating Macro for Copying data from one sheet to another,calculating the difference between dates in excel - vba

Question

The below mentioned data is for door access in a company where in we need to find the number of hours spent by a employee in office.
A employee can come in the office and swipe in and swipe out multiple times and all these details are register in the excel in non sorted order for all the employees.
I have a excel containing multiple columns
First two columns A,B are merged cells having date in this format(2015/01/25 7:27:30 PM).
The third column C has Access information having multiple entries for the below values(Entry/Exit).
For example
Column A Column B Access Employee ID Employee Name
==================================================
1. 2015/01/25 7:27:30 AM Entry 111 XYZ
2. 2015/01/25 7:30:30 AM Entry 333 ABC
3. 2015/01/25 8:30:30 AM Exit 111 XYZ
4. 2015/01/25 9:30:30 AM Entry 111 XYZ
5. 2015/01/25 9:30:30 AM Entry 444 PQR
6. 2015/01/25 10:30:30 Pm Exit 333 ABC
7. 2015/01/26 7:30:30 AM Exit 333 ABC
And so on.
Please note that the same employee can have multiple swipe in and out's throughout the day and will be clobbered among other employees information
The Goal is to as below
1) Copy the data from one sheet to another for the employees having spent time less than 9 hours for a specific day.
Here is the sample code that i have written it is work in progress
Sub HoursList()
Dim cell As Range
Dim cell1 As Range
Dim NewRange As Range
Dim NewRange1 As Range
Dim MyCount As Long
Dim ExistCount As Long
Dim ExistsCount As Boolean
Dim temp As Long
Dim MyCount1 As Long
Dim wsh As Worksheet, i As Long, lngEndRowInv As Long
Set wsh = Worksheets("Standard Door History ")
'Set cell = Range("A1")
ExistCount = 0
ExitsCount = False
MyCount = 1
MyCount1 = 1
i = 12
lngEndRowInv = wsh.Range("P" & wsh.Rows.Count).End(xlUp).Row
'----For every cell in row G on the Data sheet----'
For Each cell In wsh.Range("C12:D9085")
If cell.Value = "Entry" Then
'ExistCount = ExistCount + 1
If MyCount = 1 Then Set NewRange = cell.Offset(0, -1)
'----Sets up a new range to copy all data from the row if column in that row contains the value in question----'
Set NewRange = Application.Union(NewRange, cell.EntireRow)
MyCount = MyCount + 1
End If
Next cell
For Each cell1 In NewRange
If cell1.Value = "Mayur" Then
If MyCount1 = 1 Then Set NewRange1 = cell.Offset(0, -1)
'----Sets up a new range to copy all data from the row if column in that row contains the value in question----'
Set NewRange1 = Application.Union(NewRange1, cell.EntireRow)
MyCount1 = MyCount1 + 1
End If
Next cell1
If ExistCount > 0 Then
NewRange.Copy Destination:=Worksheets("Test").Range("A3")
End If
End Sub
Thanks

Here is a very rough version that you could use in VBA. It needs refining and error trapping, and future proofing, but it does what you want it to. It takes data from the active sheet and current adds it to the second worksheet. The date for looking up is in cell N1 of the first sheet.
Option Explicit
Sub CopyNine()
Dim LastRow As Integer
Dim DateToFind As Variant
Dim CellDate As Variant
Dim Count As Integer
Dim cel As Range
Dim DateRange As Range
Dim StaffID As String
Dim TimeStamp As Double
Dim StaffSummary As Object
Dim DS As Worksheet
Dim SS As Worksheet
Dim SSRow As Integer
LastRow = Range("A1").End(xlDown).Row
'You may wish to turn this into an input instead
DateToFind = Range("N1").Formula
Set DS = ActiveSheet
'You may wish to change this
Set SS = Sheets(2)
SSRow = 2
'Get a range containing all the correctly dated cells from the dataset
For Each cel In Range("A2:A" & LastRow).Cells
CellDate = Left(cel.Formula, InStr(1, cel.Formula, ".") - 1)
If CellDate = DateToFind Then
If DateRange Is Nothing Then
Set DateRange = cel
Else
Set DateRange = Union(DateRange, cel)
End If
End If
Next
'Create a summary dictionary of all staff IDs and their time spent in the office where 1 = 1 day
Set StaffSummary = CreateObject("scripting.dictionary")
For Each cel In DateRange.Cells
StaffID = cel.Offset(0, 3).Value
'These may need to be updated depending on your entry in the 'Entry/Exit' column
If cel.Offset(0, 2).Value = "Entry" Then
TimeStamp = -cel.Formula
Else
TimeStamp = cel.Formula
End If
If Not StaffSummary.exists(StaffID) Then
StaffSummary.Add StaffID, TimeStamp
Else
StaffSummary.Item(StaffID) = StaffSummary.Item(StaffID) + TimeStamp
End If
Next
'Copy the titles from the data sheet
SS.Range("A1:E1").Value = DS.Range("A1:E1").Value
'Copy the appropriate rows across using the dictionary you created
For Each cel In DateRange.Cells
StaffID = cel.Offset(0, 3).Value
If StaffSummary.Item(StaffID) <= 9 / 24 Then 'This is 9 hours so copy across
SS.Range("A" & SSRow & ":E" & SSRow).Value = DS.Range(cel, cel.Offset(0, 4)).Value
SSRow = SSRow + 1
End If
Next
End Sub

I would suggest using Excel's inbuilt abilities before VBA, especially if you are new to VBA. This will involve adding additional columns to your input sheet though which you can hide, but may not be ideal for your situation. It could also get quite slow as there are some large calculations, but it does depend on your original data set.
I would suggest the following (although there will be a lot of variations on it!):
1) Create a summary table for the particular day.
Create a date column in column F which is =TRUNC(A2) and copy down the table.
In M1 have your input date - e.g. 2015/01/25
In column L list all the unique Staff IDs
Below the date in M, use a SUMIFS formula and time formatting to determine how many hours each person spent. In M3 for example =SUMIFS($A:$A,$D:$D,$L2,$C:$C,"Exit",$F:$F,$M$1) - SUMIFS($A:$A,$D:$D,$L2,$C:$C,"Entry",$F:$F,$M$1) then formatting as hh:mm:ss.
In column N, use =M2<TIME(9,0,0) and drag down to work out if that individual has spent less than 9 hours in the building on that day.
You should now have a table showing all the staff and how many hours they spent in the building on that day, and a TRUE or FALSE whether they spent less than 9 hours.
2) Create your additional columns to pull the data to another sheet
In Column G, determine whether the entry is for the date in question (in cell M1) using =F2=$M$1 (should give a TRUE or FALSE)
In Column H, determine if that individual has spent less than 9 hours (from the summary table) using =INDEX(N:N, MATCH(D2, L:L,0))
In Column I, determine whether that entry should be copied across using =AND(G2, H2)
Finally in Column J, determine which entry this is to copy across using `=IF(I2, COUNTIFS($I$1:I2,TRUE),"")
Copy each of these down to the bottom of the table (you can hide them later)
3) Create your table on the next sheet for copying down - I have called my original worksheet "Data" and my second one "Copy"
In column A, use =ROW()-1 to create a sequential list of numbers
In column B, use =MATCH(A2, Data!J:J,0) to find out which row of data from the original table is being copied across
In column C, use =IFERROR(INDEX(Data!A:A,$B2),"") to pull the data from the first column
Copy this formula across to column G
Copy all of these down the sheet to however many rows of data you would like
Hide columns A, B and D since these will contain irrelevant information
You should then have an autoupdating table based on the date in cell M1 on the original data sheet. As mentioned above, this can be adapted in many ways, and it may not be ideal for your situation depending on your data set size, but it may be a start for you. If it is not suitable, then please use the theory to adapt some VBA code, as this can also be done in VBA in a very similar way.
