How this conversion works

Paste TOML into the input box and press Convert (or just keep typing, conversion happens as you type). The tool parses it with a built-in TOML parser that understands tables, arrays of tables, dotted keys and inline tables, then writes it out as comma-separated values with a header row, quoting values per RFC 4180. Conversion runs entirely in your browser with a built-in TOML parser, so your data never leaves your device.

CSV tips

CSV is the universal spreadsheet exchange format: Excel, Google Sheets, databases and data tools all import it. The first row of the output is always the header. Values containing commas, quotes or line breaks are wrapped in double quotes with inner quotes doubled, following RFC 4180, so spreadsheets import them into the correct cells. Nested objects are flattened with dot notation.
