SmarterCSV is a Ruby gem for fast, robust CSV parsing and generation, with optional C acceleration and auto-detection of messy real-world CSV formats. It returns Rails-ready hashes per row and guards against silent data corruption common in Ruby's built-in CSV library.
Use cases
- parse large csv files in ruby fast
- import user-uploaded csv files into rails activerecord
- convert csv rows to hashes for sidekiq jobs
- handle messy csv files with duplicate headers and BOMs
- preserve full decimal precision for gps or financial data
- export data to csv in ruby
- process csv files in parallel
When to choose
- you need fast, reliable CSV ingestion of real-world messy data in Ruby
- you want hashes instead of arrays for ActiveRecord or Sidekiq pipelines
- you need to avoid silent data loss like float precision rounding or duplicate headers
When to avoid
- you only need trivial CSV parsing and the standard library suffices
- your project is not in Ruby
