What Is TOML to CSV?
TOML is a config format. CSV is tabular data. TOML to CSV converts TOML tables to CSV rows. Use it when you need spreadsheet-compatible output from config. The TOML spec and RFC 4180 define the formats.
This tool runs entirely in your browser. Nothing is sent to a server. Paste TOML or upload a file; get CSV output. For JSON or YAML output, use TOML to JSON or TOML to YAML. For formatting TOML first, use TOML Formatter.
