How to Convert an EPUB File to a CSV Spreadsheet

KnowledgeBase Epub Converter offers a lightning‑fast, single‑call API that turns any e‑book (.epub) into a tidy, comma‑separated values file (.csv). Perfect for pulling tables, chapter outlines or metadata into data‑analysis pipelines, BI tools, or a simple spreadsheet.

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

  • Structure‑aware – extracts chapters, tables and footnotes as separate CSV sections (you can split or merge as required).
  • Unicode‑safe – all characters, including RTL scripts and emojis, survive the round‑trip.
  • Zero‑install – no Office, Calibre or external binaries needed; just a .NET 6+ library.
  • Cross‑platform – runs on Windows, macOS and Linux.
  • Highly configurable – control delimiter, quoting, line‑ending and table detection.

Getting Started

Add the Sheetize NuGet package and call EpubConverter.Process.

Sample C# Code 

using Sheetize;

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

var save = new SaveOptions
{
    // Destination CSV file (or folder if you split by chapter)
    OutputPath = @"C:\Exports\MarketAnalysis.csv",
};

EpubConverter.Process(load, save);

Best Practices

  1. Validate the EPUB first – a corrupted file may truncate the CSV; use an EPUB validator tool.
  2. Review the generated CSVs – adjust delimiters or quoting if your downstream system expects a specific format.
  3. Run a quick sanity check – open a few rows in a text editor or spreadsheet to confirm proper encoding (UTF‑8 is the default).
