How to Convert Excel to Markdown Using Python

When drafting documents, organizing notes, writing open-source project documentation, or conducting technical reviews, we frequently need to migrate tabular data from Excel into Markdown files. Manual copy-and-paste is not only time-consuming but also prone to formatting errors such as misaligned rows and columns, broken layouts, and missing image links.

Today I’m sharing an efficient solution: use the Spire.XLS for Python library to batch convert Excel files into standard Markdown tables in seconds. This tool natively supports combined export of multiple worksheets, custom image paths, and toggleable hyperlink formats. It requires no complicated setup and works out of the box.

1. Tool Advantages: Why Choose Spire.XLS?

Compared with mainstream Python table processing libraries like pandas and xlrd, Spire.XLS delivers standout performance for Excel-to-Markdown conversion:

• Native Format Compatibility : Fully parses .xlsx and .xls files, accurately preserves table rows, columns and text styles, and generates clean, well-structured Markdown tables without layout corruption.
• Multi-Worksheet Support : Combines all sheets within a single Excel workbook into one unified Markdown file separated by unique markers for clear structural separation.
• Customizable Asset Settings : Freely switch between relative/absolute storage paths for images and inline/reference-style display formats for hyperlinks.
• Lightweight & High-Speed : Minimal code with no redundant adaptation layers; supports batch conversion and seamless integration into automation scripts.
• Cross-Platform Compatibility : Runs smoothly on Windows, macOS and Linux, compatible with all standard Python runtime environments.

2. Environment Setup & Library Installation

First, install the Spire.XLS for Python library version 16.4.0 or newer — older versions lack Markdown export functionality. Run the commands below in your terminal:

# Install the latest Spire.XLS release
pip install spire.xls

# Upgrade if an older version is already installed
pip install --upgrade spire.xls

3. Full Working Conversion Script

This implementation delivers core capabilities: load a local Excel file, apply custom conversion rules for images and hyperlinks, merge data from all worksheets into a single Markdown file, separate each sheet with the marker ====SheetName====, and release resources to avoid memory leaks.

The complete runnable code is as follows:

from spire.xls import Workbook, MarkdownOptions

# 1. Initialize a workbook instance
workbook = Workbook()

# 2. Load your local Excel file (replace with your file path)
workbook.LoadFromFile("sample.xlsx")

# 3. Initialize Markdown export configuration
markdown_options = MarkdownOptions()

# 4. Customize conversion rules
# Store images using relative file paths
markdown_options.SavePicInRelativePath = True
# Render hyperlinks as inline links (not reference-style)
markdown_options.SaveHyperlinkAsRef = False

# 5. Export to Markdown with custom settings applied
workbook.SaveToMarkdown("custom_options.md", markdown_options)

# 6. Dispose resources to prevent memory leaks
workbook.Dispose()

print("Excel to Markdown conversion completed!")

4. Deep Dive into Core Configuration Parameters (MarkdownOptions)

MarkdownOptions is the core class that governs fine-grained Excel-to-Markdown export behavior, primarily controlling how images and hyperlinks are rendered. Key property differences are outlined below:

Configuration Property	Behavior When Set to True	Behavior When Set to False
SavePicInRelativePath	Images saved with*relative paths* Example format: Ideal for project sharing and document migration with broad compatibility	Images saved with*absolute local paths* Example format: Only works on the original device; images break after file transfer
SaveHyperlinkAsRef	Hyperlinks converted to*reference-style links* Example format:[Link Text][ref1] Recommended for lengthy URLs and streamlined long documents	Hyperlinks converted to*inline links* Example format:[Link Text](https://example.com) Intuitive and compatible with nearly all Markdown editors

5. Conversion Output Overview

5.1 Multi-Worksheet Processing Logic

If your Excel file contains multiple sheets such as Sheet1, Sheet2 and Sheet3, the script will sequentially write all sheet data into one Markdown file, with a dedicated separator header before each sheet’s content as shown below:

====Sheet1====
# Markdown table data corresponding to Sheet1

====Sheet2====
# Markdown table data corresponding to Sheet2

This separator clearly distinguishes content from different worksheets to avoid confusion and simplify subsequent review and editing.

5.2 Basic Format Preservation

Standard Excel tables are converted to valid Markdown table syntax. Cell text, layout and alignment are preserved to the maximum extent. Embedded images and hyperlinks inside cells will automatically follow the formatting rules you configured.

6. Common Issues & Optimization Tips

6.1 Images Fail to Render After Conversion

Enable SavePicInRelativePath = True to use relative paths, and store image assets in the same directory as your Markdown file to prevent broken links. Absolute paths are only suitable for temporary local previews and should never be used for project documentation or online notes.

6.2 Messy Hyperlink Formatting

For daily documents, blogs and personal notes, set SaveHyperlinkAsRef = False for clean inline hyperlinks. For large documents with a high volume of URLs, enable reference-style links to reduce clutter and shorten file length.

6.3 Batch Convert Multiple Excel Files

Wrap the core code with folder traversal logic to scan all .xlsx files in a target directory, automatically convert each one and export matching Markdown files for fully unattended batch processing.

7. Conclusion

Converting Excel spreadsheets to Markdown with Spire.XLS for Python eliminates the inefficiency and formatting chaos of manual conversion. Its standout strengths include combined multi-sheet export and granular customization of image and hyperlink rendering. The concise code integrates effortlessly into personal scripts, office automation workflows and project documentation generators.

With just two lines of configuration parameters, you can adapt the tool for local previews, open-source project publishing and document archiving, drastically boosting the speed and consistency of table document conversion.
