Top 9 C CSV Projects

CSV

  1. StringZilla

    Up to 10x faster strings for C, C++, Python, Rust, Swift & Go, leveraging NEON, AVX2, AVX-512, SVE, & SWAR to accelerate search, hashing, sort, edit distances, and memory ops 🦖

    Project mention: SIMD-friendly algorithms for substring searching | news.ycombinator.com | 2025-06-14

    Hi Austin! Was just checking your blog and the vowels detection post (< https://austinhenley.com/blog/vowels.html>).

    What exactly do you mean by “use SIMD directly without calling out to another language”?

    In some way Assembly will probably anyways be another language… but that’s a technicality.

    I guess the spectrum of SIMD-related work in relation to Python is quite broad. There are projects like PeachPy, to help one write x86 Asm in Python, new Python’esque languages like Mojo, or SIMD libraries with thin CPython bindings. Do you mean one of those?

    PS: I’m in the last camp. And in case you are focused on ASCII, for vowel search, have you tried StringZilla’s `find_first_of` (< https://github.com/ashvardanian/StringZilla/blob/960967d78c7...>)? I think it should perform well ;)

  4. zsv

    zsv+lib: tabular data swiss-army knife CLI + world's fastest (simd) CSV parser

    Project mention: How fast can you parse a CSV file in C#? | news.ycombinator.com | 2024-10-27

    Haven't yet seen any of these beat https://github.com/liquidaty/zsv when real-world constraints are applied (e.g. we no longer assume that line ends are always \n, or that there are no dbl-quote chars, embedded commas/newlines/dbl-quotes). And maybe under the artificial conditions as well.

  5. ExternData

    :page_facing_up: Modelica library for data I/O of CSV, INI, JSON, MATLAB MAT, SSV, TIR, Excel XLS/XLSX and XML files

  6. csv-nix-tools

    List system information as CSV, manipulate it, pretty print, or export.

  7. Erlang NIF CSV parser and writer

    Erlang NIF CSV parser

  8. tree-sitter-csv

    csv grammar for tree-sitter
