How to prevent OpenOffice/LibreOffice Calc from changing what you input (data, numbers,...)

Basically, I want LibreOffice Calc to do what I tell it, not what it wants.

For example:

• when I input 1.1.12, I want to have 1.1.12 in that cell, not 01.01.2012 or whatever.
• when I input 001, I want to have 001 in that cell, not 1
• and so on and so forth

I want it to never ever touch my data until I explicitly tell it to. Is that possible at all?

I know I can set format of a cell to text. It doesn't help at all. Example:

• Input 1.1.12, it gets displayed as 01.01.12, format as text, it becomes "40909", original input is lost
• Format empty cells as text. Paste "000 001 002 ..." separated by line breaks. Displays "0 1 2 ..."

I know I can write ' in front of anything for it to be forced text. Again it doesn't help, because when I paste in text, I cannot have ' auto-appended to it.

I hope this is possible. I tried googling for different problems and never found a good answer.

I understand your problem with pasting pure unformatted text. This may be more work than you like (we can try to automate that later) but when I paste data from Notepad, I am prompted with an import screen as you can see below. Select the column header(s) and then select Column type: Text. This should solve your paste/import problem. An alternative is to handle this with an AutoHotKey script.

Oh b.t.w. the @ is the format type for text, just like you have HH for 24 hour or ddd for weekdays...
