How to convert EPUB to XLAM

How to Convert an EPUB File to an XLAM Add‑in

KnowledgeBase Epub Converter provides a lightning‑fast, single‑call API that turns any e‑book (.epub) into a ready‑to‑load Excel add‑in (.xlam). Perfect for embedding book content, tables, or navigation directly into Excel dashboards, Power Query, or custom VBA projects.

Why Choose KnowledgeBase Epub Converter for EPUB‑to‑XLAM?

  • Structure‑aware – extracts chapters, tables and footnotes and packages them as VBA modules, worksheet functions or custom ribbons inside the XLAM.
  • Unicode‑safe – all characters, including RTL scripts and emojis, survive the round‑trip.
  • Zero‑install – no Office, Calibre or external binaries required; just a .NET 6+ library.
  • Cross‑platform – runs on Windows, macOS and Linux (the generated XLAM works on any Windows Excel).
  • Highly configurable – choose how content is mapped (sheets, named ranges or VBA procedures) and set the add‑in’s UI layout.
  • UK‑ready – fully compatible with Excel for Microsoft 365, Excel 2019 and Excel 2021 used across the United Kingdom.

Getting Started

Add the Sheetize NuGet package and invoke EpubConverter.Process.

Sample C# Code 

using Sheetize;

var load = new EpubLoadOptions
{
    // Path to the source EPUB file
    InputFile = @"C:\Books\FinanceGuide.epub"
};

var save = new SaveOptions
{
    // Destination XLAM file (Excel add‑in)
    OutputPath = @"C:\AddIns\FinanceGuide.xlam",
    // Optional: map each chapter to a worksheet
    MapChaptersToSheets = true,
    // Optional: generate a custom ribbon tab
    CreateRibbon = true,
};

EpubConverter.Process(load, save);

Best Practices

  1. Validate the EPUB first – a corrupted file may truncate the add‑in; use an EPUB validator tool.
  2. Review the generated XLAM – open it in Excel, check that worksheets, ranges and any generated VBA code appear as expected.
  3. Sign the add‑in – if you plan to distribute it inside an organisation, sign the .xlam with a trusted certificate.
  4. Test on target Excel versions – some newer VBA features may require Excel 2016 or later (Excel 2019, Excel 2021 or Excel for Microsoft 365).
  5. Consider localisation – if the EPUB contains UK‑specific terminology, you may wish to adjust sheet names or VBA comments accordingly.
