How to Convert an EPUB File to a CSV Spreadsheet

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

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 needed).
  • 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.
  • Highly configurable – control delimiter, quoting, line‑ending, and table detection.

Getting Started

Add the Sheetize NuGet package and invoke EpubConverter.Process.

Sample C# Code

csharp 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 default).
