Convert GNU gettext PO files from CSV files and merge them back in.

Not many translation agencies are willing to use POEdit and require to send them text to translate as spreadsheet files. This tool extracts data form PO files and stores them in CSV files, which can be opened in Excels, Google Spreadsheets, Calcs, Numbers and whatnot.

But isn't there already csv2po, which does exactly that?

Unfortunately not “exactly”. It seems not to support:

• plural forms,
• notes to translators.

node index.js file.po > untranslated.csv

Then send untranslated.csv for translation and ask to change only columns starting with “msgstr”. When you get your CSV beautifully translated do:

node index.js file.po translated.csv > translated.po
cp translated.po file.po
