Thanks @Zain_Work for replying.

It will not work for me.

I want to store values as arrays and get tham one by one and store each value in different different labels.

The result when I store data is →
30-08-23: [“2000”,“19-08-23”,“pending”]

What I want to store →
30-08-23: “[\“2000\”,\“19-08-23\”,\“Pending\”]”

Don’t use slash symbol, directly use make a list block lone. It will store the result as you expect. Do not get bore for firebase extra slash, while you retrieve automatically it will show only the data’s

I used that block but when I try to retrieve it shows errors.



Show your save block and retrieve blocks

Here is the blocks

storing data in global list

main block


Why r using add item to list???

I tried like this and got output nicely

Yes , why, what is wrong in it? Call the value of that date and use get key value block

Sorry? what is wrong?

Nothing is wrong

This isn’t json data. This data is in list shap.
You can use make a list block.

So you can easily get your stored data as like :


In list view
