I have multiple libre calc worksheets, each worksheet contains 5 till 50 sheets.
Each sheet has a colume witht the date format.
Here in Europe we try to use dd.mm.yyyy.
Unfortumally many of the colums default to yyyy.mm.dd.
I have changed them all some time ago but now after some updates many of them are back to yyyy.mm.dd
This is EASY to change for ONE sheet:
select colume # data # text to spalten (sorry in german) # now select date (JMD).
Selecting all sheets - make the change - ONLY effects ONE sheet.
How to modify all sheets in one step?
That at least reduce the work to one step for each worksheet, now it is for all sheets one step.
