Is there any way to convert .xlsx to .xls using Rails

Question

Does anybody know if there's anyway to upload a .xlsx file and then convert it to .xls file for later processing?

I'd like to use spreadsheet to write a new xls file but it doesn't support xlsx and the file is only importable with that format sadly. I saw roo but I don't know if there's a direct way to do it.

Answer 1

Use LibreOffice (free) to make your spreadsheet, it can read and write virtually any format including xls and xlsx.

I meant, any gems, to use on rails

I know you did, I was just pointing out that you could remove the problem by using LibreOffice to make the spreadsheet in the first place. If you must use MS Office then again the best solution would surely be to pay for an Office upgrade.
