XLSX and ODS no-worky!! – OOReader Review

Got conversion errors for both Excel XLSX and LibreOffice ODS files. Not sure why it didn't work. This is on an iPhone 5s with IOS 7.1.1. **December 2014** Tried the new 4.3 version and still getting various conversion errors. I appreciate that you're giving the app for free, thanks! However, the app doesn't work and has never worked for me.
