Explore real-world developer payloads and load them instantly into the editor.
A standard Stripe payment event payload with nested object structures.
A typical GitHub REST API user profile response for public profile data.
A complex nested weather API response with coordinate and system objects.
A Slack Block Kit message payload with nested blocks and accessory elements.
Simply paste your raw JSON string or API payload into the left input window pane. The online compiler engine instantly evaluates the nested object shapes and outputs copy-pasteable TypeScript interfaces in real-time.
Both represent structural layout patterns in TypeScript. However, interfaces can be extended using 'extends' and allow declaration merging, making them ideal for modeling dynamic backend API response payloads.
Click the 'Copy' pill module to store the compiled schema string in your clipboard. Paste it directly into your .ts files inside VS Code. Tip: You can turn on our optional parameters button (?) to make all property fields safely optional to prevent build errors.
If an input array contains varying primitives (e.g., strings and numbers), the client-side syntax compiler infers a union type array shape, automatically rendering the structure as (string | number)[] instead of falling back to any[].
