I regularly build apps that have semi-static data sets that I define with JSON objects.<p>Usually the client will send me something like a spreadsheet or doc and I’ll translate it into a JSON object to feed into an app.<p>The client will often then need to update the data. Instead of:<p>A) Having them send me another spreadsheet that I need to convert again then merge with the app data<p>B) Give them access to the app data directly<p>I’d love some sort of collaborative JSON editing interface that we could work on, where the schema of the object is fixed so that they can’t mess it up.<p>Does anyone know of something like this?
