Script for converting Google Discovery format into Swagger 2.0
If you need to convert some APIs from Google Discovery service I have good news for you, it is already done
I've developed this lib as part of my main project: APIs.guru - Wikipedia for Web APIs.
IMPORTANT: don't use Github RAW links because they are subject to change. Instead you can find direct links for any particular API in this list. All Swagger specs are updated, validated and fixed on daily basis.
If you have non-Google API document in this format please consider adding it to the collection: just open an issue with link to it.
If it is an internal API you can use api-spec-converter tool to do conversion for you.
