Nutrient Python SDK

Convert Word, Excel, and PowerPoint to PDF in Python

Q: How do I convert a DOCX file to PDF in Python?

Install Nutrient Python SDK. Then open the document with Document.open('document.docx') and call document.export_as_pdf('output.pdf') . The SDK handles parsing, formatting, and rendering internally with no Microsoft Office installation required. See the Word to PDF guide for a complete working example with error handling.

Q: How do I convert a PPTX presentation to PDF in Python?

Use Document.open('presentation.pptx') and call export_as_pdf() . The SDK handles slide layouts, fonts, and styling, converting each slide to a PDF page. See the PowerPoint to PDF guide for a step-by-step walkthrough.

USE CASES

When developers reach for this SDK

Convert Office files without installing Office

Linux servers and Docker containers can’t run Microsoft Office. The SDK processes DOCX, XLSX, and PPTX natively — no license, no system dependency.

Add PDF export to any Python service

Office files arrive and PDFs need to go out. Drop conversion into a Django view, FastAPI endpoint, or Celery task with two lines of code.

Deliver PDFs with enterprise-grade fidelity

The SDK maintains the original appearance of your documents — fonts, styling, and layouts are preserved through conversion. Trusted by Lufthansa, Disney, and UBS.

Produce accessible PDFs for compliance

Convert Word documents to PDF/UA-compliant output meeting ISO 14289 standards. Accessibility tagging is handled automatically by the SDK.

Frequently asked questions

How do I convert a DOCX file to PDF in Python?

Install Nutrient Python SDK. Then open the document with Document.open('document.docx') and call document.export_as_pdf('output.pdf'). The SDK handles parsing, formatting, and rendering internally with no Microsoft Office installation required. See the Word to PDF guide for a complete working example with error handling.

Do I need Microsoft Office installed to convert Office documents?

No. Nutrient Python SDK handles document parsing, formatting, and rendering internally. It processes DOCX, XLSX, and PPTX files without requiring Microsoft Office on the system, which simplifies deployment on servers and containers where Office cannot be installed.

How do I convert an XLSX spreadsheet to PDF in Python?

The API is identical to Word conversion: Open the file with Document.open('spreadsheet.xlsx') and call export_as_pdf(). The SDK handles spreadsheet layouts, cell formatting, and styles. See the Excel to PDF guide for a complete example.

How do I convert a PPTX presentation to PDF in Python?

Use Document.open('presentation.pptx') and call export_as_pdf(). The SDK handles slide layouts, fonts, and styling, converting each slide to a PDF page. See the PowerPoint to PDF guide for a step-by-step walkthrough.

Can I generate accessible PDFs that meet compliance requirements?

Yes. The SDK supports generating PDF/UA-compliant documents meeting ISO 14289 accessibility standards. When converting Word documents to PDF/UA, accessibility tagging and conformance are handled automatically. See the Word to PDF/UA guide for configuration details.

How accurate is the conversion from Office formats to PDF?

The SDK is designed to maintain the original appearance of your documents. It handles fonts, styling, layout formatting, and document structure parsing automatically. The guides describe this as preserving content in a tamper-proof form that maintains its original appearance.

Can I convert multiple documents in a script?

Yes. The SDK is a standard Python library, so you can iterate through files in a loop or use Python’s concurrency tools to process multiple documents. Each conversion follows the same two-step pattern: open and export.

How do I handle conversion errors?

The SDK uses standard Python exception handling. Wrap conversion calls in a try-except block and catch NutrientException for SDK-specific errors. Use the context manager syntax (with Document.open(...) as document:) to ensure automatic resource cleanup even when errors occur.
