Data

Format, minify, validate, and inspect JSON with error positioning for API responses, config files, and debugging logs.

Compare two JSON documents with a git-style side-by-side or unified view, structural change list keyed by JSON Path, and word-level diff for long strings.

Test JSONPath expressions and run jq filters on one page to extract nested fields, filter arrays, aggregate JSON, and see match counts as you type.

Convert JSON to YAML, XML, CSV, TOML, JavaScript object literals, and PHP arrays locally with format-specific conversion options.

Generate TypeScript, Go, Rust, Swift, Kotlin, Python, and more type definitions from a JSON sample, with inferred fields, entirely in the browser.

Convert YAML to JSON, TOML, XML, JavaScript objects, or PHP arrays. Multi-document YAML merges into a JSON array, anchors and aliases expand by default, and common traps such as the Norway problem, version-as-float, and tab indentation surface as hints.

Beautify, indent, and normalize SQL across MySQL, PostgreSQL, SQLite, BigQuery, Snowflake, and many other dialects.

Pretty print, indent, minify, and validate XML in the browser, with element folding, syntax highlighting, and line and column error reporting.

Convert XML to JSON, YAML, TOML, JavaScript objects, or PHP arrays. Elements map to keys, repeated siblings become arrays, and attributes map to prefixed fields with optional value typing.

Convert TOML to JSON, YAML, XML, JavaScript objects, or PHP arrays. TOML tables become objects, arrays of tables become arrays, and date-times plus 64-bit integers stay clear.

Minify CSS with a real parser that strips comments and whitespace, shortens values, and can merge rules, with live gzip size.

Reformat minified or one-line CSS into a readable stylesheet, with consistent indentation, one declaration per line, and your choice of indent and width.

Minify JavaScript with Terser to compress, mangle local names, and drop dead code, with live gzip size and a saved percentage.

Reformat minified or bundled JavaScript into readable code, with proper indentation, line breaks, and your choice of semicolons and quote style.

Shrink HTML and the CSS and JavaScript embedded in it, collapsing whitespace and comments while keeping the page rendering identical.

Reformat minified or one-line HTML into a readable, indented document, formatting the CSS and JavaScript embedded in it in the same pass.

Optimize and minify SVG with the svgo engine, stripping editor metadata and rounding coordinates, with a live preview and gzip size.

View, edit, parse, and export CSV in the browser with delimiter, quoting, escaping, table preview, and JSON conversion support.

Convert numbers between binary, octal, decimal, hexadecimal, and any base from 2 to 36 in the browser, with support for negatives, big integers, prefixes, and grouped output.

Convert between common units across 20+ physics and engineering categories including length, mass, duration, temperature, area, volume, speed, pressure, energy, power, information, frequency, and electrical quantities.

Convert a coordinate between WGS84, GCJ-02 (Amap/Tencent), BD-09 (Baidu), Web Mercator, CGCS2000, and global EPSG systems, with every target shown at once.
