JSON to Excel Converter CONVERSION TOOLS is a free online tool that lets you convert a JSON file into Microsoft Excel format. It has both free and paid plans for users.

If you need to convert that file from CSV to JSON, you can do that with the csvjson command like so: csvjson clients.csv > clients.json Csvkit has a couple of other handy tricks up its sleeve.
