Multilingual Excel: option to process files in "Row" format

sometimes client send Excel documents with languages under each other (row format) instead of beside each other (column format), usually the ID per term is the same, only the target language changes.

Small example:

Excel spreadsheet with three columns labeled ID, Language, and Term. Rows show language translations under each other with the same ID for terms 'Source 1' and 'Source 2'.

Would be great to see this functionality added to the filetype.
