Frequently Asked Questions
How are CSV rows represented in TOML?
As an array of tables: each row becomes a [[rows]] block with one key = value line per column, which parses to a list of objects in any TOML library.
How are value types handled?
Values that are valid integers, floats, or true/false are written unquoted so they parse as native types. Values with leading zeros (like 007) and everything else are quoted strings to avoid corrupting data.
Is CSV to TOML free to use?
Yes, completely free with no limits. No signup or download required.
Is my data private?
Absolutely. All processing happens in your browser. Your data never leaves your device.
