Dojo Toolbox
Enter keywords into the textarea (separated by new lines), then when you click Process, you will get a new string of keywords separated by the character you choose. The default separator is a comma.
How is this different from Newline to Comma?
Same idea, but you choose any delimiter instead of being fixed to commas.
Are lines trimmed before joining?
Yes — each line is trimmed so the output is clean.
Can I join with a pipe for ad tools?
Yes — set the delimiter to | for filters and feed rules.
