Free TOML to CSV converter

Why convert TOML to CSV?

People convert TOML to CSV because TOML is a configuration format, not something most tools offer to import, while CSV imports into every spreadsheet, database and analytics tool ever written.

How to convert TOML to CSV

1. Choose your TOML file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .csv. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .toml file?

TOML is a configuration format designed to be unambiguous to both people and parsers, avoiding YAML's indentation traps. Rust's Cargo, Python's packaging tooling and many Go projects use it.

What is a .csv file?

CSV is a table written as plain text: one row per line, values separated by commas. Every spreadsheet, database and programming language on earth can read and write it, which is why it remains the default way to move data between systems — at the cost of storing no formatting, no formulas and no idea what a date is.

What to expect from this conversion

Cell values are carried across exactly as they appear. Formulas become their calculated results, and formats that hold only one table — CSV and TSV — take the first sheet of a multi-sheet workbook. A CSV holds one sheet of values, so formulas, formatting and extra sheets do not come across.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your TOML file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
