Replace values in Table

Search and replace values in Table.

Documentation

Replacements will be performed in all selected columns.

Regex

If Text replace only (using regex) is checked, the search expression may be a regular expression. Here, it is possible to capture part of the match using parentheses in the search expression. To reuse the part of the match within the parentheses in the use \\1 (or higher numbers) to insert matches.

As an example let’s say that you have an input table with a column containing the strings x_old, y_old, and z_old. If you enter the search expression (.*)_old and the replace expression \\1_new the output will be the strings x_new, y_new, and z_new.

Unless configured to use regex replacement, search, replace and default values will be read as a values of the same type as the column it is replacing in. For details about how to enter values for different types, see Input typed values as text.
