I have a column Sheet1!A2:A100 with values like saga193. In Sheet2!A2:A100 I have a column, which contains some exact values from Sheet1!A2:A100, some partial values, and some different values. Partial values are like seiko saga193.
If Sheet1!A2:A100 contains saga193, and Sheet2!A2 contains seiko saga193, I want insert into Sheet2!B2 the matching value from Sheet1!A2:A100.
What is the way to do so with RegEx functions?
