JSON to Protobuf online is an online—browser-based file converter for converting from JSON to Protobuf for use in programs. Use this software when you need to convert JSON files that are used in JavaScript to Protobuf, which can be used in a variety of other programming languages.
Inspired by JSON to Go
Works directly in the browser, no installation is needed. Copy and Paste JSON file into the online tool as the input, and Protobuf is outputted instantly. Conversion Options:
- Inline Definitions
- google.protobuf.Timestamp
- Merging Similar Objects Selections Change the outpute in real-time.
