Data tools

Test regular expressions with live match highlighting.

Format, minify and validate JSON instantly.

Compare two JSON documents and highlight added, removed, and changed keys. Formatted side-by-side diff.

Paste two CSV files side by side and see which rows were added, removed or changed, instead of scanning two spreadsheets by eye.

Check XML is well formed, catching unclosed tags, mismatched element names and stray characters that break a parser before it reads any content.

Check YAML parses, and catch the indentation and tab errors that make a config file fail at deploy time rather than at the moment you saved it.

Convert TOML config into JSON and back, for when a tool wants one format and your config lives in the other.

Paste flattened or badly indented XML and get it back with each element on its own line and nesting you can actually follow.

Turn a deeply nested object into flat dot-notation keys, the shape config loaders, feature flags and spreadsheets all expect.

Run a JSONPath expression against your own document and see the matches highlighted, so you can get the selector right before it goes into code.
