How to use code to remove extra information?

You can try:

let xBreak := urlDecode("%0A");
"// Split the text into lines";
let lines := splitx('Text 2', "\n");
"// Filter out empty lines";
let nonEmptyLines := lines[!= ""];
"// Join the non-empty lines back together with newline characters";
let result := join(nonEmptyLines, xBreak);
result

I tried outJacques TUR ChatGPT for Ninox and while it didn't give me the correct answer it did lead me down this path.

I go from:

2222
333


444
555

to:

2222
333
444
555

It suggested this:

function removeEmptyLines(text : text) do
// Split the text into lines
let lines := split(text, "\n");
// Filter out empty lines
let nonEmptyLines := lines[!isempty(item(lines, i))];
// Join the non-empty lines back together with newline characters
let result := join(nonEmptyLines, "\n");
result
end;

which didn't work. Line 3 should be splitx() not split(). Line 5, the editor didn't like it. Line 7 inserts the text "\n" and not the actual new line.
