FAQ

• Q: What if my values already contain quotes?
  A: The tool wraps each line as-is, so any inner quote will still be there. Either escape it first (e.g. change ' to \') or pick the opposite quote style from the dropdown.
• Q: What array formats does "Array to Lines" accept?
  A: Standard JSON arrays ([1, 2, 3]), Python lists, or any comma-separated values with or without spaces. Elements can be numbers or quoted strings.
• Q: Does it handle Windows line endings (\r\n)?
  A: Yes. The tool splits on any line break (\r\n or \n) and silently ignores trailing blank lines.
