There isn't one specific symbol that tells a spreadsheet not to treat a cell like a value. However, depending on the spreadsheet software and what you want to achieve, here are some ways to handle this:

1. Using an apostrophe (') at the beginning of the text:

* This is the most common way to force a spreadsheet to treat a cell as text.

* For example, if you enter `'123` in a cell, the spreadsheet will see it as text, not the number 123.

2. Formatting the cell as text:

* Most spreadsheet programs have options to format cells as text, preventing them from being interpreted as values.

* This is generally done through the "Format Cells" option in the menu.

3. Using quotation marks (") around the text:

* While this is commonly used in programming languages, it might not be recognized universally in spreadsheet software. It's best to check the specific software's documentation.

4. Entering the text with a specific character:

* Some spreadsheets allow you to prefix text with a specific character (e.g., `~`, `#`) to indicate it's text. This depends on the software.

5. Using the `TEXT()` function:

* You can use the `TEXT()` function to convert a value into a text string.

* For example, `=TEXT(A1, "0")` will convert the value in cell A1 to a text string containing the number.

To clarify your request, please provide more context:

* What specific spreadsheet software are you using?

* What kind of data are you trying to enter?

* What are you trying to achieve by preventing the cell from being treated as a value?
