Case Sensitive Vlookup in Google Sheets

As you know Vlookup function is case insensitive. That means it treats small case as well as upper case letters as same. It’s not possible to use functions like EXACT with VLOOKUP to make a case sensitive Vertical Lookup. Still Case Sensitive Vlookup in Google Sheets is possible.

Here what I want to do is to find the Qty of Product IL102b which is in row # 6. But the above Vlookup formula wrongly return the result 300 from row # 5. Why? Vlookup treats IL102B as well as IL102b as same. Like most spreadsheet functions, Vlookup is case insensitive.

We can do a Case Sensitive Vlookup using a helper column as below.

Here Column A is a helper column. Now what you need to do is to use the following Regexextract Combo formula in Cell A2. Then copy and paste it to downwards up to Cell A5.

=ArrayFormula(concatenate(code(regexextract(B2, rept(“(.)”, len(B2))))))

The above same formula you can use. But rewrite the double quotes. Then apply the Vlookup formula as below.
