TOML to YAML Converter

Paste TOML configuration and instantly convert it to well-formatted YAML — all client-side, nothing sent to a server.

Use the TOML to YAML Converter

Summary

This tool converts TOML (Tom's Obvious, Minimal Language) configuration files to YAML (YAML Ain't Markup Language) format directly in your browser. It handles all standard TOML types including strings, integers, floats, booleans, datetimes, arrays, and inline tables. No data ever leaves your device.

How it works

  1. Paste or type your TOML configuration into the left panel.
  2. The converter parses your TOML in real time using a client-side parser.
  3. Valid TOML is immediately rendered as clean, indented YAML on the right.
  4. If the input contains errors, an inline error message appears — fix the TOML and output updates automatically.
  5. Click "Copy YAML" to copy the result to your clipboard.

Use cases

  • Migrate Cargo.toml dependencies to a YAML-based CI pipeline.
  • Convert Rust or Go TOML configs for tools that require YAML.
  • Translate Hugo or Zola static site config files.
  • Debug TOML structure by viewing it as YAML.
  • Learn the difference between TOML and YAML syntax side by side.
  • Batch-convert configuration snippets during a toolchain migration.
