A fast streaming CSV parser for Node.js that converts CSV into JSON objects, compatible with the csv-spectrum acid test suite. It can also run in the browser via browserify and parses around 90,000 rows per second.
Use cases
- parse large csv files in nodejs
- convert csv to json streaming
- fast csv parsing for etl pipelines
- read csv file line by line in node
- handle csv with quoted fields and newlines
- parse csv in the browser with browserify
When to choose
- you need maximum parsing throughput for large CSV files
- you want a lightweight streaming parser that pipes with Node streams
- you need broad CSV edge-case compatibility (quotes, newlines, encodings)
When to avoid
- you need to write or serialize CSV, not just parse it
- you want a Promise-based API out of the box (use neat-csv instead)
- you are not on Node.js v8.16.0 or higher
