Conversion Quality Deep Dive
Maximum of 65,536 rows × 256 columns per worksheet When this data is re-encoded into PlantUML Source, Less common than .puml but used for explicit file identification Xonvert accounts for these differences to maintain visual and structural integrity. Color accuracy is a priority in this conversion. Xonvert maintains data integrity across the format boundary. The output closely matches your original. File size after conversion depends on the content complexity and your quality settings. PlantUML Source preserves all data losslessly, so output size depends on the content's inherent compressibility.
This is a cross-category conversion from Document (Excel 97-2003) to Diagram (PlantUML Source). While these formats serve different purposes, Xonvert extracts the compatible data from your Excel 97-2003 source and maps it into the PlantUML Source format. Document files typically contain legacy spreadsheets and backward-compatible data exchange, while Diagram files are used for PlantUML diagrams using self-documenting extension. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
The XLS to PLANTUML conversion applies format-appropriate algorithms to ensure maximum data fidelity. Maximum of 65,536 rows × 256 columns per worksheet

Common Questions About XLS to PLANTUML
What's the maximum number of files I can convert at once?▼
Free users can convert several files per batch. PRO users enjoy unlimited batch sizes. For very large batches, your device's memory is the only practical limit.
Why choose PLANTUML over other formats?▼
PlantUML Source offers same PlantUML syntax as .puml with explicit extension. It's widely used for PlantUML diagrams using self-documenting extension, making it an excellent choice for most diagram needs.
Will my XLS file be deleted after conversion?▼
No. Your original XLS file is never modified or deleted. Xonvert creates a separate PLANTUML copy — your source file remains untouched.
What document quality settings should I use?▼
Default settings are optimized for the best balance of quality and file size. Adjust only if you have specific requirements.
Does this work on my phone or tablet?▼
Yes. Xonvert works on any device with a modern browser — iPhone, iPad, Android phones and tablets all supported.
Can I undo a conversion?▼
Since your original XLS file is never modified, there's nothing to undo. Your source file remains exactly as it was — only a new PLANTUML copy is created.
What if my XLS file won't convert?▼
Ensure the file isn't corrupted or DRM-protected. Try a different file to verify. If issues persist, the file may use an unsupported codec variant.
