Why Does Excel Change Numbers to Dates?
Excel's auto-formatting can be a lifesaver, but it can also be frustrating when you enter numbers that look like dates. Excel often tries to 'help' by converting entries like '1/2' or '30-06-2024' into dates, which can change the underlying value of your data.
Understanding why Excel does this is key to preventing it. In most cases, Excel assumes numbers that resemble valid date formats are intended to be dates. This tutorial helps you take control and stop this behavior.
Stop How to Excel from Changing Numbers to Dates
The solution? Explicitly tell Excel that your input should be treated as text, not a date. Here are two simple methods to achieve this:
1. Change the Format to Text: This is the most reliable method for larger datasets. Select the cell(s) where you want to enter numbers as text. Go to the 'Home' tab, click the Number format dropdown, and select 'Text'. Now, when you enter your numbers (like '30-06-2024' or '1/2'), Excel will treat them as text, preserving their original format.
2. Add an Apostrophe Before the Number: For single-cell entries, this is the quickest method. Simply type an apostrophe (') before the number. Excel recognizes the apostrophe as a text indicator, and the number will be stored as text. The apostrophe itself won't be visible in the cell, but the number will be left-aligned (indicating text). This method also works for converting existing dates to text.
Converting Convert Existing Dates to Text
If you have a column of existing dates you want to convert to text, use the apostrophe method. Add an apostrophe (') at the beginning of each date cell. Excel will then recognize the values as text rather than a date format.

Additional Tips and Considerations
You may see a small green triangle in the top-left corner of the cell, indicating that a number is stored as text. This is expected, and you can safely ignore it or click the warning and select 'Ignore Error'.
Remember to format cells as text *before* entering your numbers to ensure the correct formatting. Otherwise, the number will be converted into a date value.
