Format Converter

Auto-detects the format you paste, converts between JSON / JSON5 / JSONL / YAML / XML / TOML / CSV / TSV / SQL rows — chaining through an intermediate format when no direct conversion exists — and generates one-way code (C#, TypeScript, GraphQL SDL, HTML tables, ORM models, migrations) from data or SQL schemas.

Paste JSON, JSON5, JSONL, YAML, XML, TOML, CSV, TSV, SQL INSERT rows, or a SQL CREATE TABLE statement. The detected format is a best guess — override it with the dropdown if it's wrong; everything below (targets, code generation) follows the overridden value.

Format Converter

Universal data format converter — auto-detects JSON, YAML, XML, TOML, CSV, TSV, or SQL INSERT rows and lets you override the guess, then converts between any of them, chaining through an intermediate format when no direct conversion exists (e.g. TOML → YAML → XML). Also generates one-way code — C#/TypeScript from JSON, and ORM models or C# migrations from a SQL CREATE TABLE schema.

Common uses

  • Convert a TOML config to XML via an automatic YAML hop
  • Detect and convert a pasted CSV to JSON
  • Generate a C# class from a JSON sample
  • Generate a Prisma schema from a CREATE TABLE statement
  • Generate an EF Core migration from a CREATE TABLE statement
