Answer 1

If you already have a datatable, then you can convert a data table to a spreadsheet as easy as pie using EPPLus. The code could be as simple as this:

FileInfo f = new FileInfo("filename.xlsx");
ExcelPackage package = new ExcelPackage(f);

ExcelWorksheet ws = package.Workbook.Worksheets.Add("Data");
ws.Cells["A1"].LoadFromDataTable(table, true);

If you have some special handling, for date formats and such, it might be moderately more work, but not much.

From Nuget:

Install-Package EPPlus

If you've ever worked with Excel Interop, you will love how much easier EPPlus is to work with.

to generate xls file from json files you should done those steps

1. Read file
2. Parse JSON file (Json.NET is the best) to your c# Class object.
3. Choose xls framework(using Open XML SDK or anyone which do you find)
4. Use structure from step 2 to fill columns and rows in xls file using framework API from step 3.
