TSV to TOML Converter

Summary

This tool converts tab-separated values (TSV) data into valid TOML format entirely in the browser. Each TSV row becomes a TOML table entry under an array of tables, using the first row as the key names. No data leaves your machine.

How it works

1. Paste your TSV data (or upload a .tsv file) into the input panel.
2. The first row is treated as the header and becomes the TOML key names.
3. Each subsequent row is converted to a [[records]] table entry in TOML.
4. Numeric values are written unquoted; everything else is quoted as strings.
5. Click Copy to clipboard to grab the generated TOML output.

Use cases

• Convert exported spreadsheet data to TOML config files.
• Migrate TSV datasets into TOML-based static-site generators.
• Quickly inspect TSV structure in a more readable key-value format.
• Prepare seed data for Rust or Go apps that consume TOML configs.
• Validate column names before importing into a TOML-driven pipeline.
