Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert your EPUB e-books into structured XLSX spreadsheets effortlessly. This tool is perfect for users who need to extract data, lists, or tables from digital publications for further analysis.
EPUB is an open standard for e-books designed for reflowable content, while XLSX is a proprietary format built for tabular data and complex calculations. Converting EPUB to XLSX involves parsing the document's internal text and structure to map content into distinct spreadsheet rows and columns, making it ideal for processing structured information found in guides or catalogs.
The conversion process ensures that the text and data integrity remain intact, preserving all content without loss. File size changes remain negligible, ensuring efficiency during transmission.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
