Common Questions
Is my TOML data stored?
Nope. Everything happens right in your browser using JavaScript. Your TOML never leaves your computer – we don't even see it.
How are TOML tables converted?
The converter looks for the first array of tables, the [[name]] sections, anywhere in the file (so [[store.items]] works too). Each table in it becomes a row and its keys become the columns. Plain value arrays like tags = ["a", "b"] are skipped when looking for rows.
Does it preserve all data?
Only the rows of that first array of tables end up in the CSV; other tables and top-level keys are not included, because CSV is one flat table. Inside a row, nested tables and arrays are written as JSON text in a single cell, dates keep their TOML form, and 64-bit integers keep every digit.
Can I convert CSV back to TOML?
Not in one step, there's no direct CSV to TOML page. Go through JSON: the CSV to JSON converter gives you an array, wrap it in a key (for example {"items": [...]}), then paste it into JSON to TOML to get [[items]] tables.
Does it work with large TOML files?
Yep. Since everything happens in your browser, it depends on your device. Small to medium TOML files convert instantly. Really huge files might take a few seconds.
Is the CSV valid?
Yes! The generated CSV follows RFC 4180 specification and is valid CSV. It works with any spreadsheet application.
