Common Mistakes to Avoid

⚠️

Including blank lines

Solution: Empty lines create extra delimiters: "a\n\nb" joined with comma = "a, , b". Remove empty lines first.

⚠️

Wrong spacing in delimiter

Solution: Joining with "," vs ", " (with space) looks very different. "a,b,c" vs "a, b, c". Choose what you need.

⚠️

Not escaping output

Solution: For SQL/code use, items with quotes or special chars need escaping. Use proper quoting or sanitization after joining.
