What happens to nested objects?

They are written as text in their cell, so nothing is lost — split them further in the studio if you need to.

Can I edit the result before downloading?

Yes. The file opens in Mega Excel Studio, a full spreadsheet with an AI assistant — change anything, then download.

Is it safe to convert JSON to CSV here?

Yes. Your file travels over an encrypted connection and stays private to you — nobody else can open it. Projects you save are kept in your account until you delete them, and download links we email you expire after 7 days.

Convert JSON to CSV online, the right way

Spreadsheet apps and importers want flat CSV, not nested JSON. Drop your file, choose the options that matter, and it opens in Mega Excel Studio with the export window ready. Records become rows with a column for every key that appears in any of them. Nothing is final until you say so: fix a value, rename a heading or restyle it, then download your CSV file — or another format from the same window.

Every key a column

Keys missing from some records leave the cell empty.
