How to remove spaces between numbers, anywhere (Excel, Word or something else)?

Question

excel

Hi all. There are about 67 thousand digits. They should be written together, but now there are spaces between them. You can manually remove these spaces for 5 years. Is it possible to automatically remove all spaces so that it is not "1 234 5", but "12345"? Anywhere, I'll do it there, then I'll copy it to Excel.

Answer 1

Yes, even in a notepad, the "Find and Replace" function, put a space in the first field, nothing in the second field and go ahead.
