Traditional note on a header
EnableCommentsAttaches a classic Excel note to a header cell, giving a column an explanation on hover without spending a row on it.
Write.cs
using FormulaEngineer.Api;
using FormulaEngineer.Api.Styling;
var stylingOptions =
new ExcelStylingOptions
{
EnableComments = true
};
using (var writer = new ExcelStyledWriter("traditional-note-on-header.xlsx", null, stylingOptions))
{
using (var sheet = writer.CreateWorksheet("Notes"))
{
sheet.WriteRow("Metric", "Value");
sheet.WriteRow("Revenue", 125000m);
sheet.WriteRow("Margin", 0.184);
sheet.AddNote(
"B1",
ExcelNote.Create(
"Values in this column are produced by the reporting export.",
"John"));
}
writer.Close();
}
Style your own workbooks
Styling is part of the same package — no separate install, no Excel, no COM automation.
