Q:

How do you use REGEXREPLACE in google sheets?

I'm importing some stuff from a google form into a google sheet. I want to delete the 'time' part of the timestamp, and copy it to another spreadsheet. I'm trying to use REGEXREPLACE to do this, but REGEXREPLACE is throwing a Formula parse error.  It seems like REGEX is a different programming language altogether, so am I not using REGEXREPLACE correctly? Or am I not putting the arguments in correctly? (Btw, I'm using the more general expression so that I can use it for any "entries")
Here's the actual doc:

A:

Just replace single quotes ('') with double quotes ("").
