> My recommendation is to learn how to actually use a Json data file as a project file, parsed in via the Json object, rather than a construct array as Json.
Seems like an advice of this kind: "my car tire is flat, please help me" -> "learn how to repair the engine first".
The whole reason I'm using Construct 3 instead of Unity or Unreal is the "easy to learn no programming knowledge is required" thing. I'm not sure how making things more complicated for me will help me to make things easier. I wanted to know if there is a way to make an easy export to spreadsheet - not spend dozens (or in my case maybe hundreds) of hours learning some stuff I may not need in the future.
But thanks for an advice.
Just wanted to emphasize that for your previously stated goals, interfacing directly with JSON project files would be the most suitable. JSON is not a programming language, its a data storage format.
Rather than learning how to build a car engine, I'm trying to tell you that a proper bicycle, that other people are familiar with and know how to use (JSON is a standard, easily modifiable text file), will get you farther than a shopping cart with oars that you're going to need to teach people how to work with (fiddling with c3 arrays as json, importing and exporting between c3 and external spreadsheet software, and utilizing unsuitable formats like csv).
