How do I get non repeated letters from json ?

{

"1": [ "M A T", "C A T", "B A T" ]

}

so i want to extract non repeated letters M A T C B set into words variable

Easiest is to have an empty dictionary and then loop over each letter or each word and add that letter as a key to the dictionary. You’ll end up with one key for each unique letter. You can then loop over the keys to get the letters.

request you to show in event sheet

I won’t be able to show an image of events. But it would basically be what I wrote.

Here’s another way that just skips the json object. Basically store the json in a text variable, loop over the characters, have one condition to have it only look at letters, and a second condition to see the letter was listed yet. And finally adding the letter to a unique list.

Global text letters=“ABCDEFGHIJKLMNOPQRSTUVWXYZ”
Global text json=…
Global text unique=“”

Start of layout
Repeat len(json) times
Compare: find(letters, mid(json,loopindex,1)>-1
Compare: find(unique, mid(json,loopindex,1)=-1
— add mid(json,loopindex,1) to unique

THANX BUDDY for nice explanation
