About JSONViewerTool
JSONViewerTool provides free browser-based utilities for viewing, formatting, validating, repairing, minifying and comparing JSON. It also includes focused tools for escaping and unescaping JSON strings, converting common data formats and generating code from JSON. Developers, QA engineers, API testers, data analysts and students can inspect or transform data without installing software or creating an account.
- Who it is for
- Developers, QA engineers, API testers, data analysts and students who work with JSON and API responses.
- Problem it solves
- JSON data is often hard to inspect, compare or reuse when it is minified, malformed, nested or embedded inside another string. Developers and testers otherwise need several separate utilities or local software to format payloads, find structural changes, escape strings and convert data.
- The solution
- JSONViewerTool brings focused JSON workflows into one browser-based suite. Users can paste or upload data, format and validate it, compare two payloads, escape or unescape strings, and convert JSON to other formats without installing software or creating an account.
- What makes it unique
- The suite combines core JSON inspection, comparison, repair, schema, conversion and code-generation tools with practical guides in one free web interface. Each task has a focused URL, including dedicated JSON Compare and JSON Escape tools.
