Hello,
I have looked for a fix to my question but I didn't manage to make any of the proposed solutions work.
The find-replace tool does not give me back what I need, and fuzzy match does not quite make the trick either.
My dataset has about 200k lines, so I would avoid solutions involving permutations.
This is the situation:
I have two tables, one with item numbers, one with the "family" they belong to.
I need to look for each item in Table A inside the families of Table B, and give back the first result where a contain match is verified:

Any suggestions?
Thank you!
Ilaria
