Problem

Using python-docx the usual way (paragraph.text = ...) silently destroys run-level formatting — bold, font size, color, and other styles are lost. This plugin operates at the XML run level, preserving all styling even when text spans multiple runs.

Features

• Format-preserving text replacement — cross-run safe, handles Word's internal run splitting
• Table cell filling — write to specific cells without touching formatting
• Batch operations — replace multiple fields or fill multiple cells in one call
• Structure inspection — view table layouts with merged cell detection
