Data Format Converter
Convert YAML into JSON for APIs, frontend settings, and test fixtures.
- Paste content into any YAML, JSON, XML, or TOML pane and the other three formats will be regenerated locally in your browser.
- Use “Format Active Pane” to normalize the pane you are editing, then refresh the other formats from that source.
- The conversion pills above take you to dedicated URLs such as XML to JSON or TOML to YAML.
- Each conversion URL can be shared on its own, which is useful for SEO, docs, and internal references.
- If the source contains format-specific semantics such as YAML comments or XML-only structures, the tool prioritizes the shared data model that can travel across formats.
Tip: TOML works best for configuration-shaped data. If the input is a top-level array or scalar, the converter wraps it under root to keep the round-trip stable.
When would I use this tool?
Use it when you need to move data between API payloads, config files, RSS, SOAP, CI files, or application settings and want YAML, JSON, XML, and TOML visible side by side.
Why do dedicated URLs matter?
Because many users only care about one direction, such as XML to JSON or TOML to YAML. Dedicated URLs make sharing, indexing, and navigation clearer.
Will the content stay identical across all four formats?
Core objects, arrays, numbers, and booleans usually survive well, but comments, XML attributes, and some TOML-specific semantics are not always portable to every other format.
Why do the other panes change as soon as I edit one?
This tool uses auto-sync. Edit the format you are most comfortable with and let the other panes rebuild in the background.
Is my data uploaded?
No. Parsing and formatting happen entirely in your browser.
