Accessing Raw Cell Values with Openpyxl

When reading Excel cell values using the Openpyxl library, it's possible to retrieve the formula that calculates the value or the actual result. By default, Openpyxl returns the computed value. However, there are cases where you may need to access the raw cell value, excluding any formulas or calculations.

To read the actual cell value, you can simply set the data_only flag to True when loading the workbook. This flag instructs Openpyxl to ignore any formulas and return the value as it appears in the cell:

wb = openpyxl.load_workbook(filename, data_only=True)

This ensures that the retrieved cell value is the raw text or number stored in the cell, regardless of any formulas or calculations applied to it. This can be particularly useful when you want to access the current cell value, which may change dynamically based on other factors in the spreadsheet.

By setting the data_only flag, you can effectively bypass any computed values and obtain the true representation of the cell's content.
