Struggling to use batch macro to input multiple CSVs with different schema

jt_edin

I gather my problem is very common, and there are solutions here and here that I haven't been able to successfully implement yet.

I have dozens of CSV files in a single directory, but they have different schemas. I'd like to open them all using the *.csv wildcard, and then get Alteryx to 'union' the files based on common (or not) field names. I can then reorder the field names with a Select tool.

I have downloaded the Batch.yxzp file on this page but I don't know how to get it to work properly. I can read in my directory using the Directory tool, and pick up the FullPath (V_WString) field in the batch macro, but the output returns just one line instead of thousands. Just as the Union tool works, I'd expect all the possible field names along the tops, with <null> values in rows where certain fields are not used.

This problem must be routine. Can anyone explain how I need to reconfigure the batch macro (perhaps using the interface designer) to accomplish this task? Thanks

Go inside the macro and change the delimiter character from pipe (|) to comma (,) in the Dynamic Input tool.  That should fix it.
