I would like to hire a Coder

I would like some JS that will basically perform a vlookup. CSV1 is a list of names (column 1) paired with ID numbers (column 2). CSV2 consists of two columns as well, with names in both column 1 and column 2. Each pair of names that share a row in CSV2 are related. I would like the JS to 1) output a CSV3 with all the names in CSV2, in their same rows and columns, but with their name strings replaced by their ID numbers. I intend to use this at a workshop so several people coming to the table with their own CSV2s (likely including several of the same people but spelled slightly differently). My CSV1 will be the authority to which everyone must normalize the names in the CSVs they have brought. Ideally, the JS would include a kind of fuzzy search or predictive text function? Is there a way to provide the user with options, so they can select which name from my CSV1 best matches the (differently spelled) name in their CSV2 so that the output CSV3s are uniform for all participants? The idea would be to write a little Python or JS script that that takes (a.) a CSV with names and SDFB unique IDs and (b.) an edge list of names (but not unique IDs) and outputs an edge list using the unique IDs. This would really help participants get their data in shape for Six Degrees.
