Benchmarks of popular CSV parsers:
- Simple String.split (only non-quoted data)
- PapaParse
- csv-parser
- csv-parse
- dekkai
- fast-csv
The tests run on generated data files with 10/100 columns and 10k/100k rows, both quoted and unquoted.
The first column is numeric and used for the sum validation. The rest are just strings and not used in the tests directly.
Benchmarked on i5-8350U/16Gb RAM/SSD running Ubuntu 20.04
PapaParse was running in fast mode. Dekkai was crashing the whole process on 100k rows tests, so there are no results. We've also added a simple String.split approach here for comparison with full-featured compliant parsers. It should be treated only as a baseline.
All parsers performed a little worse on quoted data. Dekkai was crashing again on 100k rows tests and was disabled. PapaParse was running with fast mode disabled. String.split won't work for the quoted data in general and implementing proper parsing is not that trivial.
