I will have JSON from a CMS and using the JSON I want to be able to programmatically write a graphQl schema. Without needing to write the string directly.
Are there any
The json-graphql-server
project does that: Take a data JSON as input, infer types and fields from the data, write a schema containing types, queries and mutations, and start a GraphQL server schema based on that.

I know of another tool that does just the JSON to schema part, but it does not generate queries or mutations:
