hi @alrz , I’m assuming these are string columns. You may also be able to use String Manipulation (Multi Column) :
select only the columns that you want to act on, and use the following expression to replace “x” with “y”:
string(
1 == length($$CURRENTCOLUMN$$)
?replace($$CURRENTCOLUMN$$,"x","y")
:$$CURRENTCOLUMN$$)
see the “conditional expressions” paragraph here for further info:
Mind you, given the cell length to check for is 1, I think that replacing “x” with “y” could be done as a simple literal replacement, using regexReplace:
regexReplace($$CURRENTCOLUMN$$,"^x$","y")
