Convert YAML to C# online, free. YAML is an indentation-based superset of JSON favoured for human-edited config. C# classes model data for .NET with System.Text.Json support. YAML to C# conversion parses your YAML against the YAML 1.2.2 grammar (https://yaml.org/spec/1.2.2/), builds an in-memory model of its keys, nested objects and arrays, then emits ready-to-use C# types with System.Text.Json attributes following the C# language reference conventions. Processing runs in your browser in JavaScript with no upload or server round-trip — no size limit beyond your device's memory, so multi-megabyte documents convert in milliseconds and sensitive payloads never leave your machine. Typical uses include .NET APIs, desktop apps and Azure functions.
It maps the full structure of your YAML onto idiomatic C# types, following the C# language reference conventions. 100% free, no registration, and complete privacy — everything runs locally in your browser, so your data never touches a server.
Paste YAML and generate C# types from C# immediately. Conversion runs client-side, so there is no upload wait and large documents stay fast.
Nested YAML objects, tables and arrays are mapped faithfully onto C#, including nested types and optional fields.
Your YAML never leaves your device — everything is processed locally in JavaScript, with nothing logged or stored.
Unlimited conversions with no account, no quotas, and no watermark. Works on desktop and mobile.
Example: YAML → C#
public class User
{
public string Name { get; set; }
public int Age { get; set; }
public string? Email { get; set; }

YAML (YAML Ain't Markup Language) (YAML) and C# classes (C#) are different serialization formats, each with its own syntax and strengths. Data often needs to move between them when integrating tools, APIs, or configuration systems that expect a specific format. This converter maps the structure of your YAML onto valid C# so you can use it wherever C# is required.
