I have an Excel file storing a thousand lines of dates. Each date seems to be (auto)formatted as a Date. A (PHP Excel) parser I'm using (really can't update/use another one) is parsing this to a string which will occur in the number of days till 1900.
Is there a way to format the values in Excel being simple text "08.03.1991" to get this file parsed correctly?
I could add a quote: "'08.03.1991" but I need an (Excel-based) one-action-solution for all the thousand lines.
Remark: Since this is a file of a user I can't just write simple VBA-Script or so to handle this since there will be new files in the future and the User needs to be able to solve this alone.
