how to clean the wrong regular expresses in column?

[c_charles]

Hi,

I m really green hand of Calibre. Is here someone could teach me how to clean dozens of wrong regular expresses in its columns which were recorded by the software?

I assume that you are talking about failed search and replace using regexp, that caused you to loose data?

Restore your most recent backup.

With great power comes the need for great responsibility.

I typied some wrong regular expresses in those columns, and the software recorded all of these typing. My question is how to get a clean column without any wrong expresses there?

The problem, is you will likely lose other settings
Look in (use a text editor like notepad) history.plist which is found in the calibre configuration folder

Use bulk edit metadata.

Select several books and right click on them. Select Bulk Edit metadata and set the columns to any value you like. But you can't get back any previous values, just set new.
