You can use Array.AsJSON expression to get it as string. And "Array Load" action to load it back into the array.
Thanks, but Array.AsJSON assumes that you need to download the file and then upload it. But I need it to be done in the program itself without additional file downloads.
For example, I have a one-line array and I need to turn it into a string variable: 1;2;3;4;..... and then when it is necessary load it from the string variable into a single-line array
