What this tool does

TOML Validator gives you a fast, focused way to validate TOML syntax and report the number of top-level keys. Everything runs locally in this tab.

The result is produced only after the input is checked. If the value cannot be processed, the workspace reports a specific error instead of guessing.

Example

title = "Codingvila"
[tools]
private = true

Limitations

• Review important output before using it in production.
• Very large inputs remain subject to browser memory limits.
