How to Parse CSV in Rust

Use the csv crate to parse CSV files efficiently and safely in Rust. Add the crate to your project, read the file into a Reader, and iterate over records while handling errors.

[dependencies]
csv = "1.3"

use csv::ReaderBuilder;
use std::error::Error;

fn main() -> Result<(), Box<dyn Error>> {
    let mut reader = ReaderBuilder::new().from_path("data.csv")?;
    for result in reader.records() {
        let record = result?;
        println!("{:?}", record);
    }
    Ok(())
}

The csv crate is the standard tool for reading and writing comma-separated values in Rust. It automatically handles tricky details like quoted fields and different line endings so you don't have to write complex parsing logic yourself. Think of it as a specialized translator that turns raw text files into structured data your program can easily use.
