z-md-excel

Extract all Markdown tables from a .md file and save them to a formatted Excel .xlsx file.

When to Use

Trigger this skill when the user asks to:

  • Convert/extract Markdown tables to Excel
  • Export tables from a .md file to .xlsx
  • Batch extract multiple tables from one Markdown file
  • Parse Markdown table data into a spreadsheet

Requirements

  • Python 3.7+
  • openpyxl: pip install openpyxl

Usage

Command Line

# Basic usage (output defaults to <input_name>.xlsx)
python scripts/md2xlsx.py input.md

# Specify output file
python scripts/md2xlsx.py input.md output.xlsx

As Agent (recommended workflow)

  1. Identify the Markdown file the user wants to extract tables from.
  2. Ensure openpyxl is installed: pip install openpyxl
  3. Run the script: 
    python /path/to/z-md-excel/scripts/md2xlsx.py <input.md> [output.xlsx]
  4. Report results: The script prints the number of tables found and their dimensions.

Programmatic (inline Python)

import sys
sys.path.insert(0, '/path/to/z-md-excel/scripts')
from md2xlsx import extract_tables, write_xlsx

tables = extract_tables('input.md')
write_xlsx(tables, 'output.xlsx')

Output Format

  • Each table becomes a separate sheet named Table_1, Table_2, etc.
  • Header row: Bold white text on blue background, centered
  • Data rows: Regular font, auto-fitted column widths
  • Alignment: Preserved from Markdown GFM markers (:--- left, :---: center, ---: right)
  • Frozen pane: Top row frozen for easy scrolling
  • Inline Markdown stripped: Bold, italic, code, links, images are converted to plain text

How It Works

  1. Reads the Markdown file line by line
  2. Detects table blocks (consecutive lines containing |)
  3. Skips lines inside code blocks (``` fenced blocks)
  4. Requires a GFM separator row (|---|---|) to validate a table
  5. Strips inline Markdown formatting from cell content
  6. Writes all tables to a single Excel file

Limitations

  • Only supports GFM-style pipe tables (| col1 | col2 |)
  • Does not support HTML <table> elements
  • Does not preserve complex Markdown formatting (converts to plain text)
  • Nested tables are not supported
