- Convert simple JSON arrays into CSV for spreadsheets.
Limit
JSON tools check syntax, parse text, view tree structure, extract simple paths, compare JSON paths, validate pasted JSON Schema, transform valid JSON, escape and unescape string values, and convert simple tabular JSON in the browser. They do not fetch remote schema references, run full JSONPath filters, merge documents, deeply flatten complex data, authenticate APIs, store secrets, or guarantee production data contracts.
FAQ
Which JSON tool should I use?
Use JSON Formatter, JSON Beautifier, or JSON Pretty Print for readable indentation, JSON Viewer or JSON Tree Viewer to inspect nested keys and arrays, JSON Path Extractor or JSONPath Tester to pull one nested value, JSON Compare or JSON Diff to list changed paths between two snippets, JSON Schema Validator or JSON Schema Checker to validate data against a schema, JSON Validator or JSON Lint to check syntax errors, JSON Parser Online to parse pasted JSON, JSON Minifier for compact output, JSON Escape or JSON Unescape for string literals, JSON Stringify for plain text values, and JSON to CSV when you need a spreadsheet-friendly file.
Does the JSON tool upload my data?
No. JSON formatting, syntax validation, schema validation, comparison, string escaping, string unescaping, stringifying, beautifying, and minifying are designed to run locally in your browser after the page loads.
Can it validate a custom JSON schema?
Yes. Use JSON Schema Validator or JSON Schema Checker to paste data and a JSON Schema. Validation runs locally in the browser for common JSON Schema checks after the page loads.
