Top-level keys become columns; nested objects are kept as text in their field.

Can I get CSV instead?

Yes — choose CSV or Excel in the export window.

How much does it cost?

You can open your file, convert it and check or change everything in the studio before you pay anything. Downloading the finished file is part of every MojoPDF plan — start with the 7-day trial for $1 and cancel any time.

Is it safe to use Merge JSON Files 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.

Several JSON files, one list of records

Paginated API exports, daily dumps and per-user files often need to become one dataset. Drop the JSON files here and their records are stacked into one table in Mega Excel Studio — a column for every key that appears in any file, missing values left empty — so you can check, sort and clean them. Download one JSON file of records (or CSV, or Excel).
