Stop Using `diff` on CSV Files — Build a Semantic CSV Diff in 200 Lines of Python

The article discusses the limitations of using `diff` on CSV files, which can produce a 'firehose of noise' when rows are reordered or columns move. A new tool, csvdiff, is introduced which provides a semantic diff of CSV files by matching rows by a key column and reporting added, removed, or modified rows. This can be achieved in ~200 lines of Python. Engineers should consider using csvdiff for their CSV file comparisons.
