Hi, christopher-phillips,
Thanks ! So, here is the road map, with a regex S/R :
Open the Replace dialog ( Ctrl + H )
SEARCH (^|(?<=\t))"|"((?=\t)|$)|"(?=")
REPLACE Leave EMPTY
Tick the Wrap around option, if necessary
Select the Regular expression search mode
Click, exclusively, on the Replace All button
Notes :
This search regex contains 3 alternatives, separated with the alternation symbol | :
The first part (^|(?<=\t))" searches for a double quote, only if at beginning of line or preceded with a tabulation char ( \t )
The second part "((?=\t)|$) searches for a double quote, only if followed with a tabulation char or an end of line
The last part "(?=") searches for a double quote, only if followed with a second double-quote
As the replacement zone is Empty, the double-quote selected, whatever the alternative, is simply deleted
Best Regards,
