I am looking for a tool that can quickly help me compare & merge two lists with 10s or 100s of items each, showing me which items are in both lists, which only in the left list, which only in the right list, and potentially even find "almost" matches between items (similar to the clustering feature that OpenRefine seems to have for CSV files based on this really old video https://www.youtube.com/watch?v=B70J_H_zAWM - where in my case each "cluster" would consist of exactly one item from the left and right lists.
Often those two lists are lists of e-mail addresses from different sources, or lists of names where first name and last name might be ordered differently (or even inconsistently within one list).
Very simple example:Input:
Desired output (after some manual help, supported by the tool I am looking for):
Do you know any tool (within MS Excel on Windows, or as standalone tool) that can do this, with Excel or CSV as inputs? Or would you recommend I roll my own, probably leveraging GPT4 to speed up writing a python script or VBA macro?
