How HDR Handles XLS Data

Color accuracy is a priority in this conversion. Color profiles (sRGB, Adobe RGB, etc.) are preserved when both formats support them. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. HDR Image preserves all data losslessly, so output size depends on the content's inherent compressibility. Use HDR for 3D environment lighting and skybox creation For the best results, start with the highest quality Excel 97-2003 source file available.

This is a cross-category conversion from Document (Excel 97-2003) to Image (HDR Image). While these formats serve different purposes, Xonvert extracts the compatible data from your Excel 97-2003 source and maps it into the HDR Image format. Document files typically contain legacy spreadsheets and backward-compatible data exchange, while Image files are used for HDR photography. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
