Replace the old Spreadsheet Import & Export demo with a dedicated
Document Processing section: Spreadsheet API (generate XLSX/CSV from
a typed list), Import & Export (XLSX and CSV subsections, imported
data rendered in RadzenTable, configurable CSV options with live
preview), and Formulas (in-code workbook formulas, stateless
Formula.Evaluate, stateful FormulaEngine, custom FormulaFunction).
Each multi-section demo follows the H5+RadzenExample convention with
matching Toc entries. Descriptions and titles rewritten around what
users search for ("Excel", "XLSX", "CSV", "import/export",
"evaluate Excel formulas in C#") rather than internal API names.
Also ships the public FormulaEngine surface and its contract tests.
