How to Fix Excel Fill Series Not Continuing Numbers with Symbols
Question details
The user wants to generate a numbered series combined with symbols (e.g., "1#", "2#"), but Excel only repeats the first value instead of incrementing the number.
- Product
- Excel
- Device & OS
- not provided
- Scenario
- Creating a custom numbered list or sequence that includes special characters, text strings, or symbols.
- Observed behavior
- Using the Fill Handle repeats the initial alphanumeric value exactly as typed (e.g., '1#', '1#') instead of continuing the numeric sequence (e.g., '1#', '2#').
Ensure that your calculation options are set to 'Automatic' in the Formulas tab so that any sequence-generating formulas update correctly when dragged down a column.
Use the ROW Formula to Concatenate Numbers and Symbols
The most reliable way to generate a sequence of numbers with symbols is to use the ROW function combined with the desired text string.
Because Excel treats numbers mixed with symbols as text strings, the standard AutoFill handle will simply copy the value. By using a formula, you can force Excel to calculate the row number and attach your symbol to it.
Click on the cell where you want your custom sequence to begin.
Type the formula =ROW(A1)&"#" into the cell. You can replace the "#" symbol inside the quotation marks with any character or text you need.
Press Enter. The cell should now display 1#.
Click and hold the small square at the bottom-right corner of the cell, then drag it downward to instantly fill the rest of the series (2#, 3#, 4#).
Use Flash Fill for Pattern Recognition
If you already have a column with plain sequential numbers, you can teach Excel your desired text pattern using Flash Fill.

Frequently Asked Questions
Why does Excel just copy the cell when I drag down a number with text?
Excel's AutoFill feature is designed to increment plain numbers or recognized standard formats (like dates or days of the week). When you combine a number with a symbol or text string (like '1#'), Excel categorizes the entire cell contents as plain text and simply copies it instead of incrementing the numeric portion.
Can I use Custom Formatting to add symbols to a numeric series?
Yes. A highly efficient alternative is to enter plain numbers (1, 2, 3), highlight the cells, and press Ctrl+1 to open Format Cells. Go to Custom, and enter 0"#" or General"#". This changes the visual display to include the symbol while keeping the underlying value as an incrementable number.
Does the ROW formula work with letters instead of symbols?
Yes, you can concatenate letters by replacing the symbol in the formula. For example, typing =ROW(A1)&"A" and dragging it down will successfully generate the sequence '1A', '2A', '3A'.
What if I want the symbol at the beginning, like '#1'?
Simply reverse the concatenation order in your formula. Type ="#"&ROW(A1) and drag it down. The spreadsheet will output '#1', '#2', '#3' dynamically.
