I've used this article as inspiration to create a batch macro to process batches of files. The files I'm processing are simple text / csv files, however, they have a .chart extension instead of the more standard .txt or .csv. As a result, when I run my macro, I'm getting the following error: Action tool #17 has an error. The file "c:\bel02062012.chart" is not a known format (2).
The script stil runs fine, but with an error. Is there a way I can add the .chart format to Alteryx so that it is a known format.
