Will it open any .dat file?

Text-based .dat files with values separated by commas, tabs, pipes, semicolons or spaces. Binary .dat files (from games or some programs) aren't data tables.

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 DAT files 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.

DAT to CSV

Q: Why convert DAT to CSV?

A .dat file is a generic data file — usually delimited text exported by an older system; a CSV file is comma-separated values — one line per row, the format every database, CRM and online store imports. Instruments, loggers and legacy software export .dat files that spreadsheets don't recognise.

Turn .dat data exports into CSV. Every cell stays editable in Mega Excel Studio until you download.

DAT to CSV in three steps

Instruments, loggers and legacy software export .dat files that spreadsheets don't recognise. Drop your .dat file above; it opens in Mega Excel Studio with the export window set to CSV, so you can look it over, change anything and download. Delimited .dat data is split into columns and written as CSV. A CSV file is comma-separated values — one line per row, the format every database, CRM and online store imports, and opens in Excel, Google Sheets, databases, CRMs and every importer.
