Appending to a Non-Excel Text File

Written by Allen Wyatt (last updated December 5, 2023)
This tip applies to Excel 2007, 2010, 2013, 2016, 2019, and 2021


When using a macro to write information to a text file, you may want to add information to an existing file, rather than creating a new text file from scratch. To do this, all you need to do is open the file for Append rather than Output. The following code shows this process:

Open "MyFile.Dat" For Append As #1
For J = 1 to NewValues
    Print #1, UserVals(OrigVals + J)
Next J
Close #1

When the file is opened for Append mode, any new information is added to the end of the file, without disturbing the existing contents.

Note:

If you would like to know how to use the macros described on this page (or on any other page on the ExcelTips sites), I've prepared a special page that includes helpful information. Click here to open that special page in a new browser tab.
