Lock Cells in Excel using Python

This short guide describes how to lock cells in Excel using Python. You will get the IDE settings, a list of steps, and a sample code to lock specific cells in Excel using Python. All the details are provided to prepare the desired styles, which are ultimately used for locking or unlocking the cells in the Excel file.

Steps to Lock Certain Cells in Excel using Python

  1. Set the IDE to use Aspose.Cells for Python via .NET for locking the cells
  2. Apply the license to avoid the watermark and product limitations
  3. Open the Excel file using the Workbook object and select the desired sheet
  4. Set all the cells editable before unlocking them, if any
  5. Lock all the target cells using the Style class
  6. Protect the sheet once all the target cells are locked
  7. Save the output Excel file with locked cells and a protected sheet

The above steps describe the process to apply the cell protection in Excel using Python. Apply the license, load the Excel file using the Workbook object, access the sheet where cells are to be locked, optionally unlock all the objects on the sheet and make them editable, and set the locked flag to true in the style property of the target cells. Finally, call the Protect method to enforce the lock settings in the sheet and save the Workbook.
