How to replace string with value contained in cells? - vba

Question

I have a column containing formulas as "strings", i.e. "=+I11+I192+I245+I280"
I need to replace the cells (I11, I192,I245andI280`) ID with the content (strings) contained in the cells themselves.
Example:
Cell X --> "=+I11+I192+I245+I280"
Cell I11 = 'A'
Cell I192 = 'B'
Cell I245 = 'C'
Cell I280 = 'D'
The formula should generate "=+A+B+C+D".

Answer 1

This?
="=+" & I11 &"+" & I192 &"+" & I245 & "+" & I280

Answer 2

Well, how about :
=I11 & I192 & I245 & I280
Or you can include spaces
=I11 & " " & I192
But straight quotes - my phone is being funny...

Answer 3

The formula should generate --> "=+A+B+C+D"
Try,
="=+"&textjoin("+", true, I11, I192, I245, I280)

Answer 4

Don't know what you will be doing with empty cells so here is draft
Public Sub test()
[I11] = "A": [I192] = "B": [I245] = "C": [I280] = "D"
Debug.Print ConvertedString("=+I11+I192+I245+I280")
End Sub
Public Function ConvertedString(ByVal inputString As String) As Variant
Dim arr() As String, i As Long
On Error GoTo errHand
If Not InStr(inputString, Chr$(43)) > 0 Then
ConvertedString = CVErr(xlErrNA)
Exit Function
End If
arr = Split(inputString, Chr$(43))
For i = 1 To UBound(arr)
arr(i) = Range(arr(i))
Next i
ConvertedString = Join(arr, Chr$(43))
Exit Function
errHand:
ConvertedString = CVErr(xlErrNA)
End Function

Answer 5

I think you mean something like
=INDIRECT(I11,TRUE)+INDIRECT(I192,TRUE)+INDIRECT(I245,TRUE)+INDIRECT(I280,TRUE)
but please note that Indirect is a volatile function, and can slow your calculations down if used extensively.

Answer 6

Using VBA (with only single delimiter):
Function ReplaceAddr(sInput As String, Optional sDelimiter As String = "+") As String
Dim sArr
Dim i As Long
sArr = Split(sInput, sDelimiter)
For i = 1 To UBound(sArr)
sArr = Range(sArr(i))
Next i
ReplaceAddr = Join(sArr, sDelimiter)
End Function
From OP's comment:
The problem is that formulas changes, so I can't only change manually. The one I gave you is only an example, but I have so many different ones with all math operators.
You can try finding cell addresses with regular expression and replace with cell's value:
Function ReplaceAddr2(sInput As String) As String
Dim oRegEx As Object
Dim oMatches As Object
Dim i As Long, lStart As Long, lLength As Long
Set oRegEx = CreateObject("vbscript.regexp")
oRegEx.Pattern = "[A-Za-z]{1,3}\d{1,7}"
oRegEx.Global = True
oRegEx.MultiLine = True
Set oMatches = oRegEx.Execute(sInput)
lStart = 0
For i = 0 To oMatches.Count - 1
lLength = oMatches(i).FirstIndex - lStart
ReplaceAddr2 = ReplaceAddr2 & Mid$(sInput, lStart + 1, lLength) & Range(oMatches(i).Value)
lStart = lStart + lLength + oMatches(i).length
Next
ReplaceAddr2 = ReplaceAddr2 & Mid(sInput, lStart + 1, Len(sInput) - lStart)
End Function
Pattern is 1-3 letters followed by 1-7 digits.
Both functions are not volatile - will be recalculated only when input string changes, but not when cells addressed there change. Adding this line:
Application.Volatile True
will make it recalculate on every change, but it may affect performance.
