csvutil is a Go library providing fast, idiomatic, dependency-free mapping between CSV data and Go struct values via struct tags. It wraps any csv Reader/Writer implementation (such as the standard library) and supports marshaling, unmarshaling, streaming, and nested structs.

Use cases

• decode csv rows into go structs
• marshal go structs to csv
• stream large csv files into typed values
• map csv columns to struct fields with tags
• handle csv files without headers
• normalize csv data while decoding

When to choose

• you need typed CSV binding in Go with struct tags
• you want streaming decode of large CSV files
• you want to swap in a faster CSV reader/writer behind the same API

When to avoid

• you need a CSV parser itself - csvutil relies on an external reader/writer
• you work outside the Go ecosystem
• you need CSV features like type inference without predefined structs
