Frequently asked questions
- Why convert JSON to TOML?
- TOML is far more readable for configuration files than JSON because it avoids excessive curly braces and commas and supports human-friendly comments.
- How are nested objects converted?
- A nested object { "server": { "port": 80 } } is converted into a standard TOML section: [server] followed by port = 80.
- Does this tool support string arrays in JSON?
- Yes! Arrays of strings or numbers are cleanly formatted as inline TOML arrays: tags = ["alpha", "beta"].
- What happens if my JSON is invalid?
- The tool provides immediate error diagnostics pointing out missing quotes, trailing commas, or syntax errors.
- Is my input uploaded to an external server?
- No. All conversion logic runs 100% locally in your browser memory.
