Implementation Guide

We’ll break down the process of retrieving and printing worksheet names into manageable steps.

Feature: Retrieve and Print Worksheet Names

This feature focuses on extracting and displaying all worksheet names from an Excel document using GroupDocs.Viewer for .NET. Follow these implementation steps:

Step 1: Initialize Viewer with a File Path

Begin by initializing the Viewer object with your spreadsheet file path.

string filePath = "YOUR_DOCUMENT_DIRECTORY/sample.xlsx";
using (Viewer viewer = new Viewer(filePath))
{
    // Proceed to the next step...
}

Step 2: Set Up ViewInfoOptions for HTML View

Configure ViewInfoOptions to set up the HTML view of your spreadsheet. This configuration is essential for rendering the document correctly.

ViewInfoOptions viewInfoOptions = ViewInfoOptions.ForHtmlView();
viewInfoOptions.SpreadsheetOptions = SpreadsheetOptions.ForOnePagePerSheet(); // Each sheet as one page.

Step 3: Retrieve View Information

Obtain the ViewInfo object, which contains details about the document’s structure and pages.

ViewInfo viewInfo = viewer.GetViewInfo(viewInfoOptions);
Console.WriteLine("Worksheets:");

Step 4: Iterate Over Each Page and Print Worksheet Names

Finally, iterate over each page to extract and print worksheet names.

foreach (Page page in viewInfo.Pages)
{
    Console.WriteLine($" - Worksheet {page.Number} name '{page.Name}'");
}
