JSON & XML Tools is a collection of free online utilities for developers, students, and anyone who works with structured data. Every tool is designed to run entirely in your browser — your JSON and XML files are not uploaded to our servers.
What we offer
- JSON Editor Pro — tree view, format/minify, diff, JSON Schema validation, and transforms (CSV, YAML, TOON)
- JSON utilities — formatter, diff, and standalone converters
- XML Editor Pro — tree view, format, diff, XPath, XSLT, XSD validation, and converters
- XML utilities — formatter, diff, validate, XPath studio, XSLT playground, and format converters
Our mission
We want professional-grade data tools to be accessible to everyone — without accounts, without uploads, and without unnecessary complexity. Whether you are debugging an API response, comparing config files, or converting data for a spreadsheet, you should be able to do it quickly and privately.
Why choose us?
- Privacy first — processing happens locally; your documents stay on your device
- No sign-up required — open a tool and start working immediately
- Rich features — schema validation, Monaco-powered editing, side-by-side diff, and more
- Works offline — after the first load, most tools work without a network connection
- Free to use — supported by advertising on some pages
Who operates this site?
webtoolkit.in is built and maintained by Anita Kumawat, operating as Tvishi Tech Services — an independent developer-tools project based in India. I design, code, and support every tool on this site myself. There is no separate team or backend that receives your JSON or XML data; processing runs locally in your browser.
I also offer related utilities such as Image Toolkit for browser-based image compression and conversion.
Guides & learning resources
Beyond the tools themselves, we publish free guides and tutorials on JSON Schema validation, API diffing, XPath, YAML vs JSON, XML validation, and safe local editing — written for developers who need practical workflows, not marketing fluff.
