Is the first line the header?

Yes by default — turn it off if your file has no header line.

Why convert TSV to JSON?

A TSV file is tab-separated values — like CSV, but tabs between the columns, so commas inside text never need quoting; a JSON file is the data format of web APIs and apps — lists of records with named fields. Tab-separated exports need to become JSON for code and APIs.

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 convert TSV files to JSON 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 TSV to JSON — the right way

Tab-separated exports need to become JSON for code and APIs. Drop your TSV file above; it opens in Mega Excel Studio with the export window set to JSON, so you can look it over, change anything and download. Each line becomes a record named by the header line. A JSON file is the data format of web APIs and apps — lists of records with named fields, and opens in every programming language, API tool and database.
