How to Retrieve Actual Cell Values from Excel Spreadsheets Using Openpyxl When Formulas Are Present?

How to Ignore Formulas and Retrieve Actual Cell Values Using Openpyxl

When working with Excel spreadsheets that contain formulas, retrieving the underlying cell values can be challenging. Openpyxl, a popular Python library for reading and writing Excel files, allows you to access cell values without the computed formula results.

Issue: Formula Instead of Actual Value

One common issue when using Openpyxl is encountering the computed formula instead of the actual cell value. This can occur when the data_only parameter is set to True, which typically retrieves the final values after formula calculations.

Solution: data_only=True with Specific Load Option

To resolve this issue, the data_only flag can be used in conjunction with a specific loading option:

<code class="python">wb = openpyxl.load_workbook(filename, data_only=True)</code>

Here, the load_workbook method loads the Excel file while setting data_only to True. This combination ensures that formulas are ignored and the actual cell values are retrieved directly.

Conclusion

By setting data_only=True in the load_workbook method, you can retrieve the raw cell values without any formula calculations, providing accurate representation of the data in your Excel spreadsheets using Openpyxl.
