pip install git+https://github.com/tapilab/csvmerge.git

Usage

Given two files china.csv and chicago.csv:

csvmerge  -f1 china.csv -f2 chicago.csv -k2 'Global Duns No' -k1 'D-U-N-S@ Number' -o output.csv

Usage: csvmerge [OPTIONS]

  Join two csv files on specified keys and write the results.

Options:
  -f1, --from-file PATH   input file to merge FROM (.csv). This is typically
                          the smaller file.  [required]
  -f2, --to-file PATH     input file to merge TO (.csv). This can be a very
                          large file, as it is only streamed from disk, never
                          stored completely in memory.  [required]
  -k1, --from-key TEXT    field to match in the FROM file  [required]
  -k2, --to-key TEXT      field to match in the TO file  [required]
  -o, --output-file PATH  output file to write results (.csv)  [required]
  --help                  Show this message and exit.
