Libreoffice Calc: remove leading space

So I imported some data and ended up with a leading space in all the supposedly empty cells in a column. To remove, I needed to select the column then:

Edit > Find & Replace

Search For:  ^ * (i.e. a caret, a space, an asterisk)

Replace: leave blank

Click on Other Options and make sure:

  • Current selection only
  • Regular expressions

were ticked. Then Close and Replace All
