Convert IPYNB to SXW

Why Convert IPYNB to SXW?

Converting IPYNB to SXW is primarily needed when you must deliver notebook content to systems or users that rely on the legacy StarOffice Writer format. While SXW has been superseded by ODT, many government agencies, educational institutions, and organizations with older IT infrastructure still maintain documents in this format and require new content to match their existing archives.

The conversion extracts code cells and markdown documentation from Jupyter Notebooks and produces a properly formatted SXW document. Code content is presented in monospace formatting, while markdown text is converted to styled paragraphs, headings, and lists within the Writer document structure. This ensures the notebook content is readable and properly formatted in any SXW-compatible application.

SXW documents can be opened by LibreOffice, Apache OpenOffice, and their predecessors. This makes them a viable option for sharing data science documentation with non-technical stakeholders who use these office suites, particularly in environments where newer formats are not yet adopted.

Key Benefits of Converting IPYNB to SXW:

• Legacy Compatibility: Deliver content compatible with StarOffice and early OpenOffice systems
• Institutional Archives: Match existing document archives in organizations using SXW
• Document Formatting: Rich word processing layout with headings, styles, and sections
• Offline Access: Open in LibreOffice or OpenOffice without internet connectivity
• Print Ready: Proper page layout for printing notebook documentation
• Migration Path: Intermediate step when migrating from notebooks to standardized documents
• Cross-Platform: Works on Linux, macOS, and Windows via LibreOffice

Practical Examples

Example 1: Research Report to SXW Document

Input IPYNB file (notebook.ipynb):

{
  "cells": [
    {
      "cell_type": "markdown",
      "source": ["# Quarterly Performance Report\n", "## Executive Summary\n", "This report analyzes sales metrics for Q1 2025."]
    },
    {
      "cell_type": "code",
      "source": ["total_revenue = 1_250_000\n", "growth_rate = 0.15\n", "print(f'Revenue: ${total_revenue:,}')\n", "print(f'Growth: {growth_rate:.0%}')"]
    }
  ]
}

Output SXW file (notebook.sxw):

[SXW Document - StarOffice Writer Format]

Quarterly Performance Report
============================

Executive Summary
-----------------
This report analyzes sales metrics for Q1 2025.

--- Code Cell ---
total_revenue = 1_250_000
growth_rate = 0.15
print(f'Revenue: ${total_revenue:,}')
print(f'Growth: {growth_rate:.0%}')

(Document formatted with monospace paragraphs for code,
styled headings for markdown, opened in LibreOffice Writer)

Example 2: Legacy Document for Institutional Archive

Input IPYNB file (analysis.ipynb):

{
  "cells": [
    {
      "cell_type": "markdown",
      "source": ["# Environmental Monitoring Data\n", "Station readings from sensors deployed in the field."]
    },
    {
      "cell_type": "code",
      "source": ["import numpy as np\n", "temperatures = [22.1, 23.5, 21.8, 24.0, 22.7]\n", "avg_temp = np.mean(temperatures)\n", "print(f'Average temperature: {avg_temp:.1f} C')"]
    }
  ]
}

Output SXW file (analysis.sxw):

[SXW Document - StarOffice Writer Format]

Environmental Monitoring Data
=============================
Station readings from sensors deployed in the field.

--- Code Cell ---
import numpy as np
temperatures = [22.1, 23.5, 21.8, 24.0, 22.7]
avg_temp = np.mean(temperatures)
print(f'Average temperature: {avg_temp:.1f} C')

(Formatted as a StarOffice Writer document with
Heading 1 styles and Preformatted Text for code)

Example 3: Archival of Analysis Notebook

Input IPYNB file (research.ipynb):

{
  "cells": [
    {
      "cell_type": "markdown",
      "source": ["## Data Processing Log\n", "Steps taken to clean and transform the raw dataset."]
    },
    {
      "cell_type": "code",
      "source": ["df = df.drop_duplicates()\n", "df['date'] = pd.to_datetime(df['date'])\n", "df = df[df['value'] > 0]\n", "print(f'Final dataset: {len(df)} rows')"]
    },
    {
      "cell_type": "markdown",
      "source": ["### Conclusion\n", "The cleaned dataset is ready for further analysis."]
    }
  ]
}

Output SXW file (research.sxw):

[SXW Document - StarOffice Writer Format]

Data Processing Log
-------------------
Steps taken to clean and transform the raw dataset.

--- Code Cell ---
df = df.drop_duplicates()
df['date'] = pd.to_datetime(df['date'])
df = df[df['value'] > 0]
print(f'Final dataset: {len(df)} rows')

Conclusion
~~~~~~~~~~
The cleaned dataset is ready for further analysis.

(Archived as SXW with Heading 2, Heading 3,
and Preformatted Text paragraph styles)

Frequently Asked Questions (FAQ)

Q: Why would I use SXW instead of the newer ODT format?

A: SXW is mainly needed for backward compatibility with legacy StarOffice installations and institutional archives that standardized on this format. For new documents, ODT is generally preferred, but SXW ensures compatibility with older systems that cannot open ODT files.

Q: Can LibreOffice open the converted SXW files?

A: Yes, LibreOffice Writer fully supports reading and editing SXW files. It can also convert them to ODT, DOCX, or PDF for further use. Apache OpenOffice likewise supports SXW as it is the format's successor application.

Q: How is code cell content formatted in the SXW document?

A: Code cells are formatted using monospace font (Courier or similar) with a distinct paragraph style to visually distinguish them from markdown documentation. Indentation and line structure from the original code are preserved.

Q: Are notebook outputs included in the SXW file?

A: The converter focuses on the source content of cells, including code and markdown text. Execution outputs like printed results and generated plots are not included, as they are execution-specific artifacts rather than part of the notebook's authored content.

Q: Can I edit the SXW file after conversion?

A: Yes, the resulting SXW file is a fully editable Writer document. You can open it in LibreOffice or OpenOffice and modify the text, add formatting, insert images, or restructure the content as needed.

Q: Does the conversion preserve markdown headings and formatting?

A: Yes, markdown headings are converted to corresponding Writer heading styles (Heading 1, Heading 2, etc.), bold and italic text is preserved, and lists are properly formatted as Writer list items with appropriate indentation.

Q: Is there a file size limit for the conversion?

A: The converter handles standard-sized notebooks without issues. Very large notebooks with extensive embedded outputs may take longer to process, but the text extraction focuses on cell sources which keeps the SXW output compact.

Q: Can I convert the SXW to a more modern format later?

A: Yes, LibreOffice can save SXW files as ODT, DOCX, PDF, or HTML. This makes SXW a useful intermediate format when you need both legacy compatibility and the option to modernize later.
