Audit Document Conversion

audit-document-conversion

Compare a source Office document against its exported PDF to detect accessibility losses during conversion. Catches issues like lost heading structure, missing alt text, broken reading order, and missing table headers that occur when saving or printing to PDF.

When to Use It

• After exporting a Word, Excel, or PowerPoint document to PDF
• When you want to verify that Save As PDF or Print to PDF preserved accessibility
• Before publishing a PDF version alongside an Office source document
• When troubleshooting why a PDF fails accessibility checks despite the source document passing

How to Launch It

In GitHub Copilot Chat:

/audit-document-conversion

Provide both file paths when prompted:

/audit-document-conversion
Source: C:\documents\report.docx
Output: C:\documents\report.pdf

What It Does

1. Audits the source Office document for accessibility
2. Audits the output PDF for accessibility
3. Compares results to identify losses introduced during conversion
4. Reports conversion-specific issues with remediation guidance
5. Provides export setting recommendations for better conversion
