About MarkupSuite
MarkupSuite is a focused studio for markup and configuration formats: a formatter, validator, XPath tool and converter for XML, YAML and TOML in one place. Instead of hopping between half a dozen sites, you paste your data once and switch tabs.
Every operation runs entirely in your browser. There are no accounts, no ads and no analytics that sell your behaviour. The files you paste — including secrets, keys and internal configuration — never leave your device.
It is built and maintained by Interhive OÜ, a small studio in Tallinn that makes tiny, dependable web tools.
What it does
- Format & minify
Pretty-print XML, YAML and TOML with indentation and highlighting, or minify XML to a single line.
- Validate
Check that markup is well-formed, with the exact message, line and column on failure.
- Convert
Move data between XML, YAML, TOML and JSON through a common JSON hub.
- XPath queries
Extract values from XML documents with standard XPath expressions.
- Private & offline
Every operation runs in your browser; nothing is uploaded.
