- Can JOIN handle both individual cells and array ranges at the same time?
- Yes. JOIN accepts a mix of individual cell references and ranges. You can write =JOIN(", ", A1, B1:B5, C1) to join a single cell, a range, and another single cell in the same formula.
- What happens if I use a special character or symbol as the delimiter?
- The delimiter is included exactly as written in the output. For example, =JOIN(" → ", A1, B1) produces output with an arrow between the values. You can use any text, emoji, or symbol Google Sheets recognizes.
- Can I create multi-line text with JOIN?
- Yes, use CHAR(10) as the delimiter to insert line breaks: =JOIN(CHAR(10), A2, B2, C2) produces text that wraps to multiple lines when the cell is formatted for text wrapping.
- How do I join only the non-empty cells in a range?
- Combine JOIN with FILTER: =JOIN(", ", FILTER(A2:A10, A2:A10<>"")). This joins only cells that are not empty, skipping blank cells in your range.
