Stop auto correction of number into a date

Tim

I understand your frustration but this is not an autocorrect issue. 

Typing in 1/5 will automatically be recognised as a date as that is what it is unless... you signify that it is a formula and you expect the answer 0.2 to appear or it is a text item in which case you must preceed the data with a ' apostrophy.

In signifying the that the item is text you will have a data item which is left aligned, as all text is by default.  All other items in this column (even if purely numeric such as product codes) should aligned left.  Product codes though numeric should never be treaded like numbers, if you do, then expect issues.  Telephone numbers are similarly not true numbers, if they were treated as such, leading zeros would be dropped.

Though the whole idea of having to type in that extra character of ' is a pain to remember, it will make your data more acurate, reliable and portable.

If you format the cells as Text, all entries will be entered as text
(leading zeroes will be retain, date-like values won't be converted to dates, etc)
...CTRL+1 (to view the formatting dialog window)
...Select: Number_tab...Category: Text

That should resolve most (but not all) of the problem.

Does that work for you?
