XSLX translation import

I see in UI that I can download all the translations from Crowdin at an Excel spreadsheet. Perhaps I can I upload translations with the same XLSX file? Anyone knows how to do it?

Crowdin expects the translations to be in the same format as the source file, or as alternative, in XLIFF. For Excel you can do next trick:

1)Upload this Excel file into Translation Memory (resources - translation memory - update)
2)Auto-translate your existing files with the uploaded TM suggestions using pre translate
