I just came across this, and it is almost exactly what I am looking for.

My use case is slightly different in that I want the data available to plot on a chart over time.

I am trying to conceptualize (and failing) how to track a range of numbers like your January thru December into an “audit” sheet with the date/time of change and which month changed.

Ultimately to plot a line graph showing the values on the Y axis with the date on the X axis. Some values will change on the same day, while others might remain stagnant for months.

Do you think this is something that is possible?

Marcus … I was looking for this code and it works well for me. I have a large workbook (~ 10 worksheets) with up to 300 rows X 15 columns (five columns need to be tracked) and I need to track changes which your code does well. I would like to have the ‘value change data’ stored on a different worksheet sheet so as not to clutter the main worksheets with comments. Your Sub(InvertValue) does this, however can you provide info when this sub should be called and how to have separate ranges for the many worksheets?

Thanks in advance … Steve

I love this code and have been using it to help us track price changes on products that we order. Though I have a couple questions. I tried pulling the code that you made more flexible into my spread sheet and added a separate sheet to look for the cell ranges add comments to but couldn’t get it to work. I didn’t see where you had your named range “CellstoAudit”. Might be missing something. But I did get you orignal code to work perfectly for my needs. Though is it got me wondering if you could then have a code to look at the comments and highlight a cell based on the an entry into the comment box. For me I would like to have it highlight a cell if the last entry hasn’t changed in a 60-90 day time period. This would then let me know quickly if a product hasn’t been ordered based on the price not being changed in that time frame.

Hey ghellam,

Check my response to Mikhail’s comment (who had the same question.

Hey Scott,

Check my response yo Mikhail’s comment (who had the same question).

Hey Mikhail,
The handy thing about the Worksheet_Change event, is it tells you exactly which cell changed via its ‘Target As Range’ parameter.

In contrast, the Worksheet_Calculate event does not tell you which cells recalculated.

You *can*, however use the Worksheet_Calculate event to record cell updates based on formula value (result) changes like this:

Private Sub Worksheet_Calculate()
‘ Which cell(s) recalculated?

Dim Target As Range
Set Target = Range(“C7”)

If Not Intersect(Target, Range(“C2:C8”)) Is Nothing Then
Debug.Print Target.Address, Target.Value
End If

End Sub

That is, you would want to maintain a list of cells to check each time the worksheet calculated. You would need to go one step further and compare the current cell value against the prior cells value (perhaps stored in the cell’s comment) to determine if the result had actually changed before updating the audit log.

Hope this helps 🙂

Cheers,
Marcus

Hey Tiva,
In the example workbook you can download, there is a tab called ‘Audit Cells’. This lists which tabs and cells should be ‘audited’.

You will receive Error 5 when delete a row *and* the cell below it already has a cell comment.

This is because the VBA code will either try to add a new comment, or edit an existing comment.

All the best,
Marcus
