// overview
What it does
JSON minify is one of 55 tools in Hexkit, a desktop developer toolbox that runs entirely on your own machine. Strip whitespace down to a single line for embedding in headers or env vars.
Because Hexkit is a native app rather than a web page, anything you paste into the json minify stays local — there are no uploads, no accounts and no telemetry. You can reshape configs and API payloads even with the network turned off, which makes it safe for tokens, keys and production data.

How to use JSON minify
- 1
Open Hexkit and select "JSON minify", or press the command-palette key and start typing its name.
- 2
Paste your JSON, YAML, CSV or other structured data. Strip whitespace down to a single line for embedding in headers or env vars.
- 3
Read or copy the result. Everything is computed locally by Hexkit's Rust core, so nothing is ever uploaded.
Tip: the command palette opens any tool in one keystroke.
