UniversalOffice.Xlsx

Excel workbooks in pure .NET (net8.0), with no native dependencies and no Office install:

  • Read .xlsx losslessly: sheets, cells, shared and rich strings, styles, theme colors, merges, column widths, row heights, hyperlinks, comments, conditional formats.
  • Format values like Excel (Format.FormatValue): number, date, time, percent, fraction and custom format codes (pt-BR locale by default, configurable through FormatLocale).
  • Update a worksheet surgically without touching the rest of the package.
  • Export to CSV/TSV, Markdown, HTML, ODS (OpenDocument), SpreadsheetML 2003 and PDF.

Depends only on UniversalOffice.Core.

Install

dotnet add package UniversalOffice.Xlsx

Read

using UniversalOffice.Xlsx;

var package = XlsxPackage.Load(bytes);
var workbook = XlsxReader.ReadWorkbook(package);
foreach (var sheet in workbook.Sheets)
{
    var worksheet = XlsxReader.ReadWorksheet(package, sheet.Target!);
    Console.WriteLine($"{sheet.Name}: {worksheet.Rows.Count} rows");
}

// "12,5%": the default locale is pt-BR; pass new FormatOptions { Locale = … } for another one
var shown = Format.FormatValue(0.125, "0.0%").Text;

Export

using UniversalOffice.Export;
using UniversalOffice.Pdf;

string csv = XlsxCsv.ToCsv(bytes, new SheetExportOptions { SheetName = "Sales" });
string markdown = XlsxMarkdown.ToMarkdown(bytes);
string html = XlsxHtml.ToHtml(bytes, fullDocument: true);
byte[] ods = XlsxOds.ToOds(bytes);
string xml2003 = XlsxXml2003.ToXml2003(bytes);

// PDF: the generator has no built-in fonts, pass at least one TTF
byte[] pdf = XlsxPdf.ToPdf(bytes, new SheetPdfOptions
{
    Fonts = [new PdfFontSource { Bytes = File.ReadAllBytes("LiberationSans-Regular.ttf") }],
});
