I’m trying to get Code 128 barcodes generated in Excel, through the use of VBA. I’ve found a VBA class that somebody made and shared via VBForums (subsequently modified to work with Excel VBA), but I’m having problems getting it to work.
If I use the code below in an Excel Macro-enabled spreadsheet, I get the #VALUE error when trying to use the Code128_Str() function on any input.
I lack the necessary skills to debug the code properly. If this script can be corrected, I think it would be immensely useful to many people trying to do the same. The script in question uses the free font to generate the relevant Code 128 output barcodes.

Here’s how to use it
You need to have
spreadsheet)
Module
Where Class1 is the name of the Class Module
Class Module
Then in SpreadSheet, in any cell , you can call like
=Code128_Str("TESTING")or
=Code128_Str(A1)
