How it works
For BabelSheet to know how to handle your translations, you need to stick with very simple spreadsheet markup.
###- determines column with optional tags, each tag describes whole row, there might be more tags per row and they should be separated by a comma
>>>- determines column with translation key, there might be more such columns placed one after another, each column makes another key which is nested, e.g.
- locale, e.g.
pl_PLand others - determines column with translations for specific locale
Nothing is more self-explanatory then a working example.
