MS Excel 2007 XML (XLSX) is primarily a spreadsheet format used for data organization and analysis, supporting complex formulas and tables. In contrast, AZW3 is an Amazon Kindle proprietary eBook format optimized for displaying text and images on e-readers. While XLSX files focus on tabular data, AZW3 files are designed for readable content presentation.
Keep individual XLSX files under 10–50 MB for fastest, most reliable conversion; large spreadsheets with hundreds of sheets may cause slowdowns or truncation.
Preserve quality by embedding images in common formats (JPEG/PNG) and avoiding extremely high DPI; set image DPI to 150–300 for a balance of clarity and file size.
For best reading flow, simplify complex layouts: merge or flatten multiple tables, convert intricate charts to images, and move essential narrative text to dedicated cells or a single sheet.
Use batch conversion for multiple files, but process large batches in smaller groups (e.g., 5–10 files) to avoid timeouts; consider zipping files if the converter accepts archives.
