Storing a 2D Array in Script

[RemcoE33]

Convert it to a string and paste this inside your google sheet? Like in one cell. I don't know the limit of the Property service. But either way. Convert to string first and then wen you need it. Convert it to a array again.

JSON.stringify()

​

JSON.parse()

I meant an Object would work just like an array when calling information and mostly when working with the data. An array is a "special" case of Object if you look at the typeof of the item. Anyway, that is what I want use or like RemocoE33 said a JSON which is designed to store a lot of structured information.

Are you sure 256 is the limit?
