Why Most Users Prefer the Web UI Over Python CLI
IBM's Docling is an extraordinary engineering achievement, but running it locally is notoriously difficult for non-programmers. It requires:
- Python 3.10+ and a dedicated virtual environment (`venv` or `conda`)
- Over 4GB of downloaded deep learning model checkpoints (PyTorch, TableFormer, EasyOCR)
- Properly configured NVIDIA CUDA drivers and cuDNN libraries; otherwise CPU mode takes 40+ seconds per page
- System dependencies like
libgl1-mesa-glxthat frequently cause runtime crashes on Linux and Windows
With SheetParser, you bypass all technical friction. Cloud servers scale to zero when idle and spin up dedicated GPU workers on demand, delivering your structured Markdown in 2-3 seconds per page.
