ICU Message Formatter
ICU Message Formatter handles the small but fussy part of working with icu message and variables. Paste a real example, adjust the option when one is available, and inspect the result beside the source. Processing stays in the browser, so it is useful for quick drafts, debugging, and one-off checks without setting up a package or command-line tool.

What this tool does
This tool parses the supplied icu message and variables and produces formatted message using rules suited to ICU Message Formatter. It reports useful counts so you can spot unexpectedly empty or broad results.
The browser parses the input, applies the selected rule set, and creates both a readable output and structured export data.
Always compare generated or extracted output with the original source before replacing production code or translations.
Example
Load the sample and select Format ICU Message. The result demonstrates the exact output format, including any inferred types, matches, or validation notes.
Use cases
- Draft code or configuration from a representative sample.
- Inspect unfamiliar source before editing it.
- Run a quick browser-side check during debugging.
- Export a result for review or documentation.
Tips for better output
- Use a representative input, not only the shortest possible sample.
- Keep a copy of the original before applying generated output.
- Test empty, null, and Unicode values where relevant.
- Resolve every warning instead of assuming the output is complete.
- Run a project-specific formatter or validator afterward.
Processing details
All core parsing and transformation is performed with JavaScript in the current browser tab. No external API key or build step is required.
This lightweight tool focuses on common syntax. Project conventions, advanced schemas, locale rules, and compiler-specific checks may require a dedicated parser or build tool.
Frequently asked questions
Does ICU Message Formatter send my input to a server?
No. The conversion runs in your browser, although the page itself may load normal site resources.
What input does ICU Message Formatter accept?
Paste the source text shown by the input label and use the sample as a format guide.
Can I use the output without reviewing it?
Treat the result as a starting point. Check naming, types, escaping, and project-specific conventions before shipping it.
Why did the tool report an error?
The input may be empty, malformed, or missing a required option. The error message identifies the first condition the tool could not process.
Can I download the result?
Yes. Use Download TXT for the main output. When structured rows or JSON are available, the matching export buttons appear after processing.
