Google Spreadsheets Regex Case Insensitive (Regexreplace)

Question

I\'m trying to create a case insensitive regex query in Google Spreadsheets with the regexreplace function. Is that possible? I\'ve tried the \\i flag and got a #REF error s

Answer 1

AFAIK, the only way to enable case-insensitive matching is JavaScript API in google docs.

Apparently, RE2 syntax does support the inline (?i) case-insensitive modifier:

=REGEXREPLACE("Test", "(?i)t", "")

An alternative that will work is using a Character class, adding both cases of the letter T..

=REGEXREPLACE("Test", "[Tt]", "")
