Export Tips and Troubleshooting for Python
This page covers tips, common issues, and frequently asked questions for exporting spreadsheets with Aspose.Cells FOSS for Python.
Tips and Best Practices
Markdown Export
- Use
MarkdownHandler.save_markdown_to_string(wb)for in-memory use cases such as API responses.
CSV Export
- CSV export writes the first worksheet by default.
- Special characters (commas, newlines) in cell values are automatically quoted.
JSON Export
- JSON export uses cell addresses as keys. Suitable for data interchange; complex formulas are stored as their string expressions.
Common Issues and Resolutions
| Issue | Resolution |
|---|---|
ModuleNotFoundError: No module named 'aspose.cells_foss' | Run pip install aspose-cells-foss and confirm the virtual environment is active |
AttributeError on SaveFormat.PDF | PDF export is not in the FOSS library; use SaveFormat.MARKDOWN or SaveFormat.XLSX instead |
| Empty Markdown output | Ensure at least one cell in the sheet has a value before saving |
| Encoding issues in Markdown | Use MarkdownHandler.save_markdown_to_string() for in-memory string output with full encoding control |
Frequently Asked Questions
Which output formats does Aspose.Cells FOSS support? XLSX, CSV, TSV, Markdown, and JSON.
Can I convert to PDF?
No. PDF export requires the commercial aspose-cells-python package. Aspose.Cells FOSS exports only to XLSX, CSV, TSV, Markdown, and JSON.
Can I load an existing XLSX and re-save it as Markdown?
Yes. Workbook("existing.xlsx") loads the file, and workbook.save_as_markdown("output.md") exports it.
Is stream-based Markdown output supported?
Yes. Use MarkdownHandler.save_markdown_to_string(workbook) to get the Markdown as a Python string without any file I/O.
What Python versions are supported? Python 3.7 and later.
