XLS files are still commonly used for maintaining financial data, reports, and internal records in many organizations. These spreadsheets may include text watermarks to indicate ownership, approval status, or confidentiality. When preparing files for sharing or publication, such watermarks often need to be removed. If you want to remove text watermark from XLS using Python, a Python-compatible spreadsheet processing API allows you to detect and remove watermark text automatically. This guide also explains how to delete watermark in Excel using Python, offering a controlled and code-driven approach to spreadsheet cleanup.

Steps to Remove Text Watermark from XLS Using Python

1. Install GroupDocs.Watermark for Python via .NET to enable text watermark cleanup in Excel files
2. Bring in the watermark processing package and its search criteria dependency
3. Start processing by opening the XLS spreadsheet through the Watermarker class
4. Define the target watermark phrase using the TextSearchCriteria configuration
5. Analyze worksheet content and remove all matching text watermark entries
6. Save the XLS file after successfully removing the watermark text

Using a spreadsheet watermark removal library, XLS files can be examined for text-based watermark content embedded across worksheets. By defining search rules, the API identifies watermark text without interfering with formulas, formatting, or cell values. Once detected, the watermark entries are removed while preserving the integrity of the spreadsheet. This approach is especially useful for automated workflows that process large numbers of legacy Excel files. By following these steps, you can implement Python code to remove watermark from XLS efficiently and maintain consistent results across different spreadsheet datasets.

Code to Remove Text Watermark from XLS Using Python

After the watermark removal process is complete, the XLS file is clean and ready for distribution or archival use. Customizable search criteria make it easy to adapt the solution to different watermark text patterns across multiple workbooks. This flexibility ensures reliable long-term automation for spreadsheet management tasks. By applying this workflow, you gain a dependable way to clear watermark in XLS using Python while preserving data accuracy and layout. Overall, this method provides a practical and automated solution for maintaining professional, watermark-free Excel spreadsheets.
