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 PowerPoint presentations directly into Excel spreadsheets with our seamless PPTX to XLSX tool. This is the perfect solution for users who need to extract tabular data from presentation slides for financial analysis or reporting.
PPTX files are designed for visual storytelling, organizing content into individual slides, whereas XLSX files are structured as data grids optimized for calculation and mathematical processing. When you convert PPTX to XLSX, our engine identifies embedded tables and data-driven charts within your slides and maps them into the cells, rows, and columns of a standard spreadsheet. This transformation bridges the gap between presentation-ready visualizations and raw data management.
The conversion maintains complete data integrity; all numerical values and text labels within your tables are transferred without loss of quality. The file size remains largely unchanged as the underlying data structure is simply re-mapped into the spreadsheet format.
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.
