Ask HN: Interactive CSV Diffing Tool?
How would you best diff two csv-s in 2021 ?
And not just full matches, column by column too.
Especially if you want to compare many thousands of rows.
- jstx1 5y agoI would use something like pandas or dplyr (Python and R libraries respectively). But that's for answering specific questions like finding duplicates, missing values, overlapping columns etc. - in my experience there's usually some more specific question to answer than just diffing in a general sense.
- marto1 5y agoThat's great. I use these myself on a daily basis, but it can turn into quite a grind, especially working with novel(to me) datasets.
