Overview

Managing Excel spreadsheets with hidden sheets is common when dealing with complex data sets or protecting certain information. Retrieving these hidden sheets can be crucial when working on reporting, data validation, or debugging. With the FileFormat.Cells SDK, developers can easily programmatically access hidden sheets in Excel files. This guide will show you how to retrieve hidden sheets from a Microsoft Excel spreadsheet using C#.

Get Hidden Sheets from Excel with FileFormat.Cells

Retrieving hidden sheets

Retrieving hidden sheets from an Excel file using the FileFormat.Cells SDK is simple and efficient. Whether for data extraction, verification, or auditing purposes, accessing hidden sheets allows you to manage Excel workbooks more effectively.

Here is the complete code to hide a worksheet, also available on GitHub Gist:

Explanation:

  • Workbook: This class represents the Excel workbook. In this example, we are loading the workbook from a file path using the Workbook class from the FileFormat.Cells SDK.
  • GetHiddenSheets(): This method retrieves a list of hidden sheets from the workbook. The returned list contains tuples with the sheet’s ID and name.
  • Tuple<string, string>: The hidden sheets are stored as tuples where the first item is the sheet ID, and the second item is the sheet name. This allows you to identify the hidden sheets easily.

How it Works:

  1. Load the Workbook: First, you need to load the workbook from the specified file path using the Workbook class.
  2. Retrieve Hidden Sheets: The GetHiddenSheets() method is called to return a list of hidden sheets.
  3. Display Hidden Sheets: Each hidden sheet’s ID and name are printed to the console using a simple loop.

This code simplifies accessing hidden sheets and allows for seamless integration into larger workflows where you need to manage or reveal hidden data.
