About Indentio

A focused tool for developers who work with XML and JSON every day and are tired of hunting for the one character that broke everything.

What it does

Indentio formats, minifies, validates, and repairs XML and JSON. Unlike tools that only say “invalid”, it highlights the exact line and column of each error, explains it in plain English, and offers a one-click fix for common mistakes.

How it works

The whole app runs client-side in your browser. It’s built withAstro for a fast, lightweight static site andCodeMirror for the editor, with battle-tested parsing and repair libraries doing the heavy lifting. Because nothing is sent to a server, it’s both fast and private.

Your privacy

We never receive the documents you paste — they are processed entirely on your device and are never uploaded, logged, or stored. See our privacy policy for details.

Roadmap

• JSON ⇄ XML conversion
• Schema validation (XSD / JSON Schema)
• JSONPath and XPath querying
• Shareable, self-contained permalinks (still without server storage)
