How to verify translation before official build

I finished Metabase translation and want to verify it. There are some build scripts in github, but not sure how to execute them (in windows OS). I expect some java command or standalone tool.

@CZvacko You would have to replace the translations manually Regexextract in Custom column or build your own version

Manual JSON-file replacement in the JAR-file is fine, but PO file conversion is unclear. POeditor support export into JSON directly, but internally its not same format, right ?
Building own version is not the way I want to go.

@CZvacko That’s the only way possible right now. We don’t have a separate way for translators to check their strings.
The i18n build scripts will download the PO files from POEditor and makes small adjustments to the format and converts them to JSON.
