Yes, it is possible to populate a comment on a worksheet using a smart marker in Aspose.Cells. You can utilize the SmartMarker feature to dynamically insert comments based on your data source.

Here’s a simple example of how to do this:

  1. Prepare your template Excel file with a smart marker for comments, for example, {{Comment}}.
  2. Use the following C# code to populate the comment:
// Load the template workbook
Workbook workbook = new Workbook("Template.xlsx");

// Create a data source
DataTable dataTable = new DataTable();
dataTable.Columns.Add("Comment");
dataTable.Rows.Add("This is a comment.");

// Set the data source
workbook.Worksheets[0].Cells.ImportDataTable(dataTable, true, "A1");

// Process smart markers
workbook.CalculateFormula();
workbook.Save("Output.xlsx");

In this example, replace "Template.xlsx" with the path to your template file and ensure that the smart marker {{Comment}} is placed in the appropriate cell where you want the comment to appear.

Please note that the smart marker feature is designed for use with Excel files, and comments will be inserted based on the data provided in the data source.

Are you talking about the Comment/Note object attached to one Cell? If so, this feature is not supported currently. It will be better to help us understanding your requirement if you can provide one sample file that contains the expected result so we may evaluate it further.

Yes.

This is what I’m thinking of:

And once workbook designer processes the template file, what I’m looking for is:

Given:

{
    "name": "John Doe",
    "age": 30,
    "user_comment": "name has been updated"
}

Let me know if this provides the whole picture.

It’s threaded comments in your demo image, not note. The feature more looks like a chat. Please confirm you want to add comment or note?
Will you want to come style of the smart note/comment?

Note is fine for my use case.
