It was a great idea to release an extension like that, but in my case it generates empty XLXS's for some reason 😔

This app is a great tool for anyone who needs to quickly and easily convert their CSV files to XLSX format. It's easy to use and does a great job of preserving the data in the original file, so you can be sure you're getting great results every time. Highly recommended!

Great extension, works well when it does. I have had a bit of problem making it work with a domain other than Google, at the moment. Hope the dev. fixes it. Recommend it to anyone that requires automatically converting their .csv files to .xlsx with no additional steps.
