How Do I Change Data Type in Excel?


Heather Bennett

Changing the data type of a cell or range in Excel is a fundamental skill that every user should master. Whether you need to convert text to numbers, change a date format, or switch from one data type to another, Excel provides several options to accomplish this task. In this tutorial, we will explore different methods to change data types in Excel.

Using the Format Cells Dialog Box

The Format Cells dialog box is a powerful tool for customizing the appearance and behavior of cells. To change the data type using this method:

  1. Select the cell or range of cells you want to modify.
  2. Right-click on the selection and choose Format Cells from the context menu.
  3. In the Format Cells dialog box, go to the Number tab.
  4. Select your desired data type from the list on the left-hand side.
  5. Click OK to apply the changes.

Note: When changing data types using this method, make sure you select an appropriate format that matches your data. For example, if you have dates stored as text, select a date format from the list; if you have numbers stored as text, choose a number format.

Using Formulas

If you want more control over how your data is converted, you can use formulas to change data types. Here are some common examples:

To convert text to numbers:

If you have numeric values stored as text in Excel, you can use the VALUE function to convert them into actual numbers. Simply enter the following formula in an empty cell:


Replace A1 with the cell reference containing the text value you want to convert. Copy the formula down to apply it to multiple cells if needed.

To convert numbers to text:

If you want to convert numbers into text format, use the TEXT function. This function allows you to specify a custom number format as a string. For example:


This formula converts the numeric value in cell A1 into a text value with two decimal places.

To convert dates:

If you need to change the date format in Excel, use the TEXT function as well. Specify the desired date format using appropriate placeholders (e.g., “dd/mm/yyyy” for day/month/year). Here’s an example:


This formula converts the date in cell A1 into a custom date format with dashes separating day, month, and year.

Using Paste Special

The Paste Special feature in Excel allows you to perform various operations while pasting data. To change data types using this method:

  1. Copy the cells containing the original data.
  2. Right-click on a destination cell and choose Paste Special from the context menu.
  3. In the Paste Special dialog box, select Values.
  4. Click OK.

This method copies only the values without any formatting or formulas, effectively changing the data type of your selection to match that of the destination cells.

In Conclusion

Changing data types in Excel is an essential skill that can help ensure accurate calculations and proper data analysis. Whether you prefer using the Format Cells dialog box, formulas, or the Paste Special feature, Excel provides multiple options to suit your needs. Experiment with these methods and discover which one works best for your specific data type conversion requirements.
