Replace tag with text in a textbox inside the Worksheet

Possible Usage Scenarios

Text boxes can have tags which can be replaced with some text at run time to configure them according to the requirement. Tags can be some labels enclosed in angle brackets ‘<’ and ‘>’. There can be multiple tags within a single textbox.

Sample Code

Following sample code replaces tags TAG_1 and TAG_2 with some text say ‘ys’ and ‘1’. Sample file for testing below code can be downloaded from the following link:

sampleReplaceTagWithText.xlsx

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-.NET
Workbook wb = new Workbook(sourceDir + "sampleReplaceTagWithText.xlsx");
string tag = "TAG_2$TAG_1";
string replace = "1$ys";

for (int i = 0; i < tag.Split('$').Length; i++)
{
    sheetReplace(wb, "<" + tag.Split('$')[i] + ">", replace.Split('$')[i]);
}
PdfSaveOptions opts = new PdfSaveOptions();

wb.Save(outputDir + "outputReplaceTagWithText.pdf", opts);

public static void sheetReplace(Workbook workbook, string sFind, string sReplace)
{
    string finding = sFind;

    foreach (Worksheet sheet in workbook.Worksheets)
    {
        sheet.Replace(finding, sReplace);

        for (int j = 0; j < 3; j++)
        {

            if (sheet.PageSetup.GetHeader(j) != null)

                sheet.PageSetup.SetHeader(j, sheet.PageSetup.GetHeader(j).Replace(finding, sReplace));

            if (sheet.PageSetup.GetFooter(j) != null)

                sheet.PageSetup.SetFooter(j, sheet.PageSetup.GetFooter(j).Replace(finding, sReplace));

        }

    }

    foreach (Worksheet sheet in workbook.Worksheets)
    {

        sFind = sFind.Replace("<", "&lt;");
        sFind = sFind.Replace(">", "&gt;");

        foreach (Aspose.Cells.Drawing.TextBox mytextbox in sheet.TextBoxes)
        {


            if (mytextbox.HtmlText != null)
            {
                if (mytextbox.HtmlText.IndexOf(sFind) >= 0)
                {
                    mytextbox.HtmlText = mytextbox.HtmlText.Replace(sFind, sReplace);
                }
            }
        }
    }
