Search

  • 2 min to read

To search for specific data in a range, worksheet or entire document, use the CellRange.Search, Worksheet.Search or Workbook.Search methods, respectively. To set options affecting search in a document, create an instance of the SearchOptions class and pass it as a parameter to the Search method. You can set the following advanced options.

workbook.Calculate();
Worksheet worksheet = workbook.Worksheets["ExpenseReport"];
workbook.Worksheets.ActiveWorksheet = worksheet;

// Specify the search term.
string searchString = DateTime.Today.ToString("d");

// Specify search options.
SearchOptions options = new SearchOptions();
options.SearchBy = SearchBy.Columns;
options.SearchIn = SearchIn.Values;
options.MatchEntireCellContents = true;

// Find all cells containing today's date and paint them light-green.
IEnumerable<Cell> searchResult = worksheet.Search(searchString, options);
foreach (Cell cell in searchResult)
    cell.Fill.BackgroundColor = Color.LightGreen;

The image below shows the result of executing the code (the workbook is opened in Microsoft® Excel®). Today's date is located in the expense report and highlighted in light-green.
