DOCX Shell Extraction

When to Use This Skill

Use this pattern when you need to read or extract text from Microsoft Word (.docx) files in constrained environments where:

• The python-docx library is not available
• You cannot install additional Python packages
• You need a quick, reliable shell-based solution

Core Technique

DOCX files are ZIP archives containing XML files. The main document content is stored in word/document.xml. You can extract and parse this using standard shell tools.

Step-by-Step Instructions

Step 1: Extract the document.xml content

unzip -p filename.docx word/document.xml

The -p flag pipes the content to stdout without extracting to disk.

Step 2: Strip XML tags to get plain text

unzip -p filename.docx word/document.xml | sed 's/<[^>]*>//g'

This removes all XML tags, leaving the text content.

Step 3: Clean up whitespace (optional)

For cleaner output, add additional sed processing:

unzip -p filename.docx word/document.xml | \
  sed 's/<[^>]*>//g' | \
  sed 's/&[^;]*;//g' | \
  sed 's/^[[:space:]]*//' | \
  sed 's/[[:space:]]*$//' | \
  sed '/^$/d'

This removes:

• XML tags
• XML entities (like &, <)
• Leading/trailing whitespace
• Empty lines

Step 4: Save to a text file (optional)

unzip -p filename.docx word/document.xml | \
  sed 's/<[^>]*>//g' > output.txt

Complete Example

# Extract text from a Word document
DOCX_FILE="report.docx"
OUTPUT_FILE="report_text.txt"

unzip -p "$DOCX_FILE" word/document.xml | \
  sed 's/<[^>]*>//g' | \
  sed 's/&[^;]*;//g' | \
  sed '/^$/d' > "$OUTPUT_FILE"

echo "Extracted text saved to $OUTPUT_FILE"

Verification

After extraction, verify the content was captured:

# Check if output file has content
if [ -s "$OUTPUT_FILE" ]; then
    echo "Successfully extracted $(wc -l < "$OUTPUT_FILE") lines"
    head -5 "$OUTPUT_FILE"
else
    echo "Warning: Output file is empty"
