API Get help

[Novodk]

The data looks tab-separated. This code will split the data into separate lines and then each line into separate items.

Code:

lines = data:split('\n')
for _, line in ipairs(lines) do
  items = line:split('\t')
  log(items)
end

Okay, I have had some time to look at this again, and I admit I need more help.
The code you provided put the data into separate items, that I should be able to put in group addresses with the grp.checkupdate, but I can't get it working!
