Appending to a Non-Excel Text File

by Allen Wyatt
(last updated November 18, 2016)

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.

Understand that the information in this tip shows how to add data to a text file; it doesn't indicate where that data should come from. In other words, if you want the data to come from information stored in variables in your macro, you'll need to determine which variable contents to write to the file. (The example code actually uses variables—the UserVals array—for writing information to the text file.) If, however, you want the information to be pulled from a worksheet, then you'll need to create the code that grabs the information from the desired cells and, in turn, writes it out to the text file. (This tip is not about grabbing the data, but about writing it to the file.)
