THE UNIVERSAL
JSON WORKBENCH

Yes. JSON-Kit runs entirely client-side. All parsing, formatting, validation, compression, and conversion happens locally in your browser.

This applies to all tools includingJSON Formatter,JSON Editor,JSON Validator,JSON Parser, andJSON Lint.

Your data is never uploaded, stored, or logged.

Most JSON files under 50MB process instantly depending on your device.

For large payloads, useJSON Minifier orJSON Compressor. Visual tools likeJSON Visualizermay slow down on very large files.

• JSON Formatter & Beautifier
• JSON Validator
• JSON Lint
• JSON Parser
• JSON Editor
• JSON Viewer
• JSON Visualizer
• JSON Diff
• JSON Minifier
• JSON Compressor & Decompressor
• JSON to CSV
• JSON to XML
• JSON to YAML

Use theJSON Validatorto detect syntax issues like missing commas or invalid quotes.

For deeper diagnostics, useJSON Lint orJSON Parserto see exact error locations and parsing behavior.

JSON-Kit supports:

• CSV, XML, YAML
• Excel-ready tables
• SQL insert statements

After conversion, optimize output usingFormatter,Minifier, orCompressor.

The JSON Viewer is read-only and optimized for safely inspecting large JSON structures and API responses.

The JSON Editor allows you to modify, add, delete, and reorder JSON data with real-time validation.

JSON Validatorsimply checks whether JSON is valid or invalid.

JSON Lint goes deeper by explaining why the JSON is broken, highlighting exact line numbers, and suggesting fixes.

JSON parsing converts a JSON string into a JavaScript object, similar to how JSON.parse() works.

You can test real parsing behavior using theJSON Parserto catch syntax errors before using JSON in your application.

Minificationremoves whitespace and formatting (~30–40% reduction).

Compression(Gzip/Brotli) encodes the data for transport, often reducing size by 70–90%. Best practice is to use both.

Yes. Use theJSON Difftool to compare two JSON files side-by-side.

Differences in values, keys, and structure are highlighted clearly, making it ideal for configuration audits and API response comparisons.
