EasyFormatConverter is a collection of free online tools to convert data formats — JSON, YAML, CSV, XML, TOML — and to generate typed code (TypeScript, Python, Go, Rust) from JSON samples.
Privacy by design
Every conversion runs entirely in your browser. There is no upload endpoint, no processing server: the code that does the work is downloaded with the page and executes locally. You can load a tool, disconnect from the internet, and it keeps working. That makes these tools safe for API keys, customer data and anything else you would not paste into a random website.
Free, fast and to the point
No account, no paywall, no cookie banner. Each tool does one conversion well, with real-time output, syntax highlighting and proper handling of the edge cases that break naive converters — quoted CSV fields, YAML anchors, XML attributes, TOML tables.
Built by developers
These are the tools we wanted ourselves: open them, paste, copy the result, get back to work. If a conversion looks wrong or a format is missing, feedback is always welcome.
