Modern development often requires moving data between different environments—from a raw API response to a frontend interface, or from a database to a backend service. mula.dev is a lightweight, client-side workbench that automates the "busy work" of JSON manipulation.
TypeScript Interface: Converts JSON keys into typed definitions. Perfect for React/Vue developers who want to avoid any types.
Go Struct: Automatically generates structs with PascalCase names and the correct json tags for the Go language.
Prettify: Expands minified JSON into a readable, indented format—essential for debugging messy API logs.
Minify: Removes all whitespace and newlines. Use this to reduce the payload size of configuration files or data sent over a network.
Input: Paste your JSON data into the left panel.
Selection: Pick your conversion or formatting task from the dropdown menu.
Execute: Press Run Task.
Export: Click Copy Output to move the result to your clipboard.
Note on Privacy: All processing is done locally in your browser. Your data is never sent to a server.
