This brief guide contains information on how to update Excel using Python by providing detailed instructions to configure the environment and then sharing a step-by-step process to perform this task. To update Excel file Python sample code is shared that introduces all the necessary classes and functions required to update the source XLSX file. Once the update task is completed, the output file is saved as XLSX. Moreover, you can save it to any other MS Excel supported format like XLS, ODS, etc.

Steps to Update Excel using Python

1. Setup the environment to work with Aspose.Cells for Python via Java
2. Load the source Excel file into the Workbook class object to be updated in Python
3. Get access to a Cell and update its value
4. Get access to some other cell and set formula in it
5. Call the Calculate function to refresh the Excel file after updating the contents
6. Save the updated Excel file on disk in the desired format

These steps describe this task with the help of a simple to-do tasks list. However, you can update Excel sheet using Python where advanced and complex components are used in the source file. For changing the Excel file, you have to access the particular cell in the selected worksheet and then use setValue() function to set the desired contents. Similarly, the formulas can be set using the setFormula() function in conjunction with the calculateFormula() function at the end to update the entire workbook with reference to the latest contents.

Code to update Excel Sheet using Python

While we update Excel Python code imports necessary classes in the beginning and then loads the desired workbook. You can set values and formulas in the cells using the specified functions; however, you can also manipulate slicers, tables, pivot tables and perform other advanced tasks like adding comments to cells, creating auto-filters, implementing data validations, merging and splitting cells, and protecting/un-protecting worksheets.
