Common Mistakes to Avoid

⚠️

Different line ending types

Solution: Windows uses \r\n, Unix uses \n. Tool may handle only one type. Normalize first.

⚠️

Extra line break at end

Solution: Trailing newline may add extra separator at end. Trim text first to avoid.

⚠️

Empty lines creating double separators

Solution: Blank lines become just the separator. Remove empty lines first for clean output.
