Data Tools

Data tools cover everything for reading, converting and cleaning structured formats: JSON, CSV, YAML, XML and TOML. Pretty-print messy JSON, check its syntax before sending it to an API, turn a CSV export into JSON for a script, or move between configuration formats in one click.

Every operation runs entirely in your browser — your files, including those holding tokens, customer records or personal data, never leave your machine. Handy for debugging an API response, preparing a dataset or migrating a config without installing anything.
