UPDATE - Excel Macro to Combine Multiple Spreadsheets Into One


The Tip of the Night for October 13, 2016 showed how to use a macro to combine multiple Excel workbooks. At the request of a visitor to this site, I have edited the VBA code so that it will collect all of the populated cells on each worksheet (assuming the data begins at A1 and there are no gaps.) The previous version of the code required that the user estimate the maximum range of data on the source Excel files. On the line which begins:

Set sourceRange =

. . . we could enter A1:K25, if we were certain that none of the Excel files to be merged had more than 25 rows or more than 11 columns. This would necessitate opening and reviewing each source file or making a pretty good guess. If would also leave the new spreadsheet created with the macro with lots of extra blank rows that would take additional steps to eliminate.

In this version of the macro the line setting the range has been updated to:

Set sourceRange = .Range("a1", Range("a1").End(xlDown).End(xlToRight))

Which goes from cell A1 to the end of the entered text. Now the resulting spreadsheet with all of the data from the source files won't have unnecessary blank rows.

[the text editor for my Wix site may alter the formatting of the VBA Code. If it doesn't work go to the my source for the code here and enter in my edit on your own.]
