How to retrieve excel sheet names (list spreadsheet worksheets)

Below is a step‑by‑step guide that walks you through extracting worksheet names. The code remains unchanged from the original example, ensuring it runs as‑is.

Step 1: Initialize the Viewer

Begin by initializing Viewer with your document path:

try (Viewer viewer = new Viewer("YOUR_DOCUMENT_DIRECTORY/three_sheets.xlsx")) {
    // Initialization code here...
}

This block sets up the Viewer to work with a specified file, ensuring proper resource management using try‑with‑resources.

Step 2: Configure ViewInfoOptions

Set ViewInfoOptions for HTML view information retrieval:

ViewInfoOptions viewInfoOptions = ViewInfoOptions.forHtmlView();
viewInfoOptions.setSpreadsheetOptions(SpreadsheetOptions.forOnePagePerSheet());

This configuration ensures each worksheet is rendered separately, facilitating easier iteration over individual sheets.

Step 3: Retrieve and Display Worksheet Names

Obtain the ViewInfo object to get details about document pages (worksheets):

ViewInfo viewInfo = viewer.getViewInfo(viewInfoOptions);

for (Page page : viewInfo.getPages()) {
    System.out.println(" - Worksheet " + page.getNumber() + ": '" + page.getName() + "'");
}

This loop iterates through each worksheet, printing its index and name. It’s the core of the java extract xlsx sheets operation.

Troubleshooting Tips

  • Ensure File Path Accuracy: Double‑check your document path to avoid file‑not‑found errors.
  • Version Compatibility: Use compatible GroupDocs.Viewer library versions with your Java environment.
