Free CSV to Go Converter — generate a typed Go struct from CSV columns in your browser

What Is CSV to Go Conversion?

CSV to Go conversion turns the columns of a CSV file into a typed Go struct describing one row. Each header becomes a field, and the converter infers the Go type from the column values — whole numbers become int, decimals become float64, true/false becomes bool, and everything else stays string. That gives you a struct ready to use with encoding/csv or a CSV-decoding library, instead of hand-writing field types.

How Type Inference Works

CSV cells are untyped text, so to produce a professional struct the tool scans all rows of each column and picks the narrowest fitting type:

  • int — every non-empty value is a whole number.
  • float64 — every value is numeric and at least one is a decimal.
  • bool — every value is true or false (any case).
  • string — the fallback for mixed, text, or empty columns.

How to Use the CSV to Go Converter

  • Paste CSV with a header row into the input, or load the example.
  • Click Convert to Golang to generate the struct.
  • Copy the result into your .go file and decode your CSV into it.

Common Use Cases

Decode a CSV export into typed Go values, scaffold a model for a data importer or ETL job, generate fixtures for tests, or quickly map the shape of an unfamiliar spreadsheet — all in your browser, with nothing uploaded.

Frequently Asked Questions

Does it infer int and bool, or is everything a string?

It infers types. Columns become int, float64 or bool when every value qualifies; otherwise the field is string.

Does the struct represent one row or the whole file?

One row. Decode your CSV into a slice of the struct (e.g. []Row) to hold all records.

Will it add CSV struct tags?

The converter emits clean field names and types; add csv:"..." tags for your specific decoder if it requires them.

Is my CSV uploaded to a server?

No. Conversion runs entirely in your browser — your data never leaves your device.
