## What it is
XML Notepad is a free Windows desktop application from Microsoft for browsing and editing XML documents with a tree view and text view. It includes schema-aware Intellisense, XPath search, XSLT transforms, XML diff, and conversion of CSV/JSON/HTML files to XML.

## Use cases
- edit xml files with a gui
- browse large xml documents in a tree view
- run xslt transforms and preview output
- compare two xml files for differences
- convert csv or json to xml
- find nodes with xpath or regex

## When to choose
- you need a dedicated Windows GUI editor for XML with schema validation and Intellisense
- you want to inspect, diff, or transform XML documents quickly
- you work with large XML files and need fast loading and incremental search

## When to avoid
- you need a cross-platform XML editor on Linux or macOS
- you only need programmatic XML parsing in code rather than a visual editor
- you need JSON or YAML as your primary format

## Facets
- artifact type: application
- maturity: active
- function: editor, developer-tools, parser
- domain: developer-tools, files, windows
- platform: windows
