Google Sheets: COUNTIF, ARRAYFOMULA, FILTER, REGEXMATCH, REGULAR EXPRESSIONS (RE2)
Okay, wait! Stop!…
…I know the byline contained regular expressions, but I promise you I won’t just leave you with the formula for you to figure out your own jumbled mass of jibberish characters or inundate you with a list of commands and leave to attempt to piece it all together.
I promise to give you some clear examples with an explanation of each to you can apply it to your project.
Take a deep breath, mate, and let’s get cracking.
We are going to look at two related scenarios:
Imagine that you have a huge list of items. You have a hunch that some of the cells contain certain values of interest for you. You want to build a new list with only those values in them.
Imagine that you have a list of full names, and you want to use Google Sheets to create a new list of full names that only contain John.
You have that same huge list again, but this time you only want the total count of all the rows that contain certain values in each cell.
Imagining that list of full names again, you are now going to get a total count of all full names that contain John in it.
We’ll first go through how to create these formulas and then provide a number of clear examples on some common criteria for searching cell for values using REGEXMATCH and regular expressions.
