Troubleshooting
IPYNB to PDF errors
Most export issues come from content that was not saved in the notebook or from a print layout that needs adjustment.
Charts or output are missing
Run the source cells in your notebook environment, confirm the chart or output is visible, and save the `.ipynb` file again. This converter intentionally does not run code to recreate missing results.
Code or tables are cut off
Keep long-line wrapping enabled, try landscape orientation, or choose a wider paper setting. The preview scrolls wide tables so you can spot a layout issue before printing.
The notebook will not open
Confirm that the file is valid JSON in a supported nbformat 3 or nbformat 4 structure and is under 20 MB. A file with a `.ipynb` extension can still be malformed or partially downloaded.
Interactive widgets do not match
Widgets and JavaScript-dependent charts need a static saved representation. Export or save a static image from the notebook environment when possible.
