Stop autoformating text as date

Trying to input a string as text and Calc autoformats it as a date no matter what I try. Tried everything I could think of myself first and then tried everything I could find on this commmunity. So far, no luck at all. I don’t really want any autoformating at all but this date thing is crucial.

What exactly did you try? Detailed explanations help to identify root cause and solution. E.g what text string did you enter? Did you copy & paste from somewhere or enter text via your keyboard? Which OS and LibO version are you using?
