Transforming & Loading BEFORE combining

[alramirez]

I have a folder with hundreds of CSV files (one new added every month, each one about 10 MB) and need to transform all these files into smaller versions of themselves (about 100k each) and load them into a new folder.  How can I do that in Power Query, without having to combine all the original, large files into a single query?

Hi @alramirez ,

PowerQuery does not provide the feature of exporting. It is recommended that you consider using Python with the Pandas library for file conversion.
