Question 1

How to parse a CSV string with neat-csv in Node.js?

Accepted Answer

Use the neatCsv function with a CSV string, Buffer, or stream. For example, await neatCsv('name,age
Alice,30') returns an array of objects like [{name: 'Alice', age: '30'}]. The README provides a straightforward async/await example for quick integration.

Question 2

neat-csv vs csv-parser: which is better for my use case?

Accepted Answer

neat-csv is better for simple, promise-based parsing without streaming needs, while csv-parser is superior for handling large files with streaming or when you require fine-grained control. Choose neat-csv for convenience and csv-parser for performance with streams.

Question 3

Can neat-csv handle CSV files with custom delimiters or headers?

Accepted Answer

Yes, you can pass an options object to customize parsing. For instance, use { separator: ';' } for semicolon-delimited files or { headers: false } to disable header mapping. All options from csv-parser are supported, as noted in the API documentation.

Question 4

Is neat-csv suitable for serverless environments with memory limits?

Accepted Answer

It may not be ideal due to its in-memory parsing; for serverless apps with strict memory constraints, consider using csv-parser directly with streaming to process data incrementally and avoid high memory usage.

Question 5

How do I handle errors when parsing CSV with neat-csv?

Accepted Answer

Wrap the neatCsv call in a try-catch block since it returns a Promise. Errors from the underlying csv-parser will be thrown, and you can handle them like any async operation, but note that parsing issues should be reported to csv-parser's repository.

Question 6

Does neat-csv support converting CSV to JSON arrays directly?

Accepted Answer

Yes, it automatically converts CSV rows to JavaScript objects with headers as keys, outputting a JSON-like array. For example, parsing 'id,value
1,test' gives [{id: '1', value: 'test'}], making it easy to integrate into JSON-based workflows.
