Aspect RST (Source Format) TXT (Target Format)
Format Overview
RST
reStructuredText

Lightweight markup language developed by the Python community in 2001. Primary format for Python documentation, Sphinx, and Read the Docs. Emphasizes simplicity and readability with explicit, consistent syntax for technical documentation.

Python Standard Sphinx Native
TXT
Plain Text

The simplest and most universal document format. Contains only readable characters without any formatting markup. Readable by any text editor, operating system, or programming language. The foundation of digital text communication.

Why Convert RST to TXT?

Converting reStructuredText (RST) documents to plain text removes all markup syntax, leaving only the readable content. This is useful when you need the pure text content without RST's directives, underlines, and special characters.

Plain text is the most universal format - it works everywhere, requires no special software, and will remain readable indefinitely. When you need to share documentation content with someone who doesn't have RST tools, or need to process text programmatically, TXT is the simplest solution.

The conversion is particularly valuable for text mining and natural language processing tasks. Machine learning models, search indexers, and text analysis tools work best with clean plain text without markup interference. Converting RST to TXT creates ideal input for these applications.

Plain text files are also perfect for inclusion in emails, terminal output, or systems that don't support rich formatting. The conversion strips RST's visual markup while preserving the logical structure through whitespace and simple indentation.

Key Benefits of Converting RST to TXT:

  • Universal Access: Readable on any device without special software
  • Content Extraction: Pure text for processing and analysis
  • Smaller Size: No markup overhead means smaller files
  • Text Search: Grep, search tools work perfectly
  • Email/Chat: Paste content anywhere without formatting issues
  • Archival: Future-proof format that never becomes obsolete
  • NLP Ready: Clean input for text analysis and ML models

Example 2: Code Documentation

Input RST file (api.rst):

API Reference
=============

The ``calculate()`` function accepts these parameters:

:param x: The first number
:param y: The second number
:returns: The sum of x and y

.. code-block:: python

   result = calculate(5, 3)
   print(result)  # Output: 8

Output TXT file (api.txt):

Frequently Asked Questions (FAQ)

Q: What happens to RST formatting when converting to TXT?

A: All RST markup is removed or simplified. Bold/italic markers are stripped, directives are converted to labeled text, headers lose their underlines, and links are converted to inline URLs. The result is clean, readable text.

Q: Are code blocks preserved?

A: Yes, code content is preserved with simple indentation. The syntax highlighting directive information is removed, but the actual code text remains intact and properly indented for readability.

Q: What encoding is used for TXT output?

A: The output uses UTF-8 encoding by default, which supports all Unicode characters from your RST source. This ensures special characters, symbols, and non-ASCII text are preserved correctly.

Q: How are RST tables converted?

A: Tables are converted to simple text representations. Grid tables may use ASCII characters to maintain structure, while simple tables become space-aligned text. Complex tables may need manual adjustment for optimal readability.

Q: Can I use the TXT output for text analysis?

A: Absolutely! Plain text is the ideal format for NLP, machine learning, and text analysis tools. The conversion removes markup noise, leaving clean text that tokenizers and analyzers can process efficiently.

Q: What about images and embedded content?

A: Images and embedded content cannot be represented in plain text. Image directives are converted to placeholder text showing the image path or alt text. Consider this when documentation relies heavily on visual content.

Q: Is there any way to preserve some structure?

A: The conversion preserves logical structure through whitespace: blank lines separate sections, indentation shows hierarchy, and lists use simple markers. Headers remain as text but without underline decoration.

Q: Can I convert TXT back to RST?

A: Plain text lacks the semantic information needed to recreate RST markup automatically. You would need to manually add headers, directives, and formatting. Consider keeping your RST source files if you need to edit the documentation.
