CSV & spreadsheets tools

The files people most need to convert are the ones they least want to upload — an export of your customer table is not something to hand to a free web converter. Everything here parses in your tab, including the awkward parts: quoted delimiters, newlines inside fields, BOMs, semicolon exports and rows with the wrong field count.

Convert

CSV → JSON

Convert to JSON with column types inferred, not everything stringified.

CSV → SQL

Generate CREATE TABLE and INSERT statements with types inferred per dialect.

Code generation

CSV → types

Generate TypeScript, Go, Rust, Python, Java, C# or Zod types from the columns.

Inspect

CSV analyzer

Profile every column: type, nulls, distinct values, ranges and bad rows.
