JSON to Excel is one more free online tool that lets you convert a JSON file into multiple formats. You can upload a JSON file from your computer or by pasting the URL of the remote JSON file.

The task of converting JSON to an Excel CSV file won’t take a long time. We suspect it can take less than a minute if you move fast enough and have the relevant knowledge.

That shouldn't be a problem, after all, Excel can handle JSON. So, you try to open the file in Excel using its data import tooling, which usually works very well indeed as a basic ETL system.

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.
