Markdown vs Text Files

When to write .md and when to write .txt —
a clear-eyed comparison with side-by-side examples.

Format Overview

Markdown  (.md)

Advantages

  • Rich formatting — headers, bold, italics, lists, links, tables
  • Syntax highlighting — beautiful fenced code blocks
  • Structured hierarchy — clear document outline
  • Modern integration — native in GitHub, VS Code, Confluence
  • Rendered previews — looks polished in supported tools

Disadvantages

  • Requires a renderer — raw view shows markup symbols
  • Learning curve — need to know the syntax
  • Slight size overhead — formatting markup adds bytes

Plain Text  (.txt)

Advantages

  • Universal compatibility — opens in anything, everywhere
  • Print-ready — reliable on paper, no renderer needed
  • No dependencies — future-proof for decades
  • Smaller files — no markup overhead
  • No learning curve — just type

Disadvantages

  • Visual monotony — all text looks identical
  • No code highlighting — code blocks are harder to read
  • Limited structure — only capitalisation and spacing

Detailed Feature Comparison

Feature Markdown Plain Text
Headers & Structure Excellent Basic
Code Formatting Syntax Highlighting Plain Text Only
Universal Compatibility Requires Renderer 100% Compatible
File Size Slightly Larger Smaller
Print Quality Renderer-Dependent Always Reliable
Visual Appeal Modern & Structured Monotone
Learning Curve Moderate None
Modern Toolchain Fit Native (GitHub, VS Code) Basic Support
File Size Reality Check
Same content, two formats:
  • Markdown file: ~3.2 KB
  • Plain text file: ~2.8 KB
  • Difference: roughly 12% larger
Why the difference?

Markdown includes formatting symbols: **, #, *, -, backticks. At document scale this is negligible.

Side-by-Side Examples

Markdown

# Main Title ## Subtitle ### Section Header #### Subsection ##### Small Header

Plain Text

MAIN TITLE ========= SUBTITLE -------- Section Header -------------- Subsection ----------

Markdown

```javascript function greet(name) { return `Hello, ${name}!`; } ``` Inline: `const x = 5;`

Plain Text

function greet(name) { return `Hello, ${name}!`; } Inline: const x = 5;

Markdown

## Unordered - First item - Second item - Nested item ## Ordered 1. First step 2. Second step ## Checklist - [x] Done - [ ] Pending

Plain Text

UNORDERED * First item * Second item - Nested item ORDERED 1. First step 2. Second step CHECKLIST [X] Done [ ] Pending

Markdown

**Bold text** *Italic text* ***Bold and italic*** ~~Strikethrough~~ > Important blockquote **WARNING:** Critical info!

Plain Text

BOLD TEXT /Italic text/ ***BOLD AND ITALIC*** --Strikethrough-- > Important blockquote >>> WARNING: Critical info!

When to Use Each Format

Choose Markdown When…

  • Creating documentation for GitHub, GitLab, or Confluence
  • Writing study guides or spec files with code examples
  • Building README files for any project
  • Collaborating in VS Code or a modern editor
  • Publishing technical content to the web
  • Producing interactive or structured learning materials
Best for Digital Use Modern Workflow

Choose Plain Text When…

  • Printing documents on paper without a renderer
  • Universal compatibility with any device is required
  • Working in a terminal, SSH session, or legacy environment
  • Sending email attachments to non-technical recipients
  • Creating long-term archival documentation
  • Quick scratch notes with no formatting needs
Best for Print Universal Access

The Bottom Line

For technical documentation, spec files, and collaborative development, choose Markdown. For printing, archiving, or environments without a renderer, plain text is the safer choice.

Use Markdown for:

  • Digital studying and review
  • Code examples and walkthroughs
  • Spec files and developer notes
  • GitHub repos and documentation sites

Use Plain Text for:

  • Printing reference sheets
  • Quick notes in any environment
  • Long-term archival backups
  • Sharing with non-technical audiences

Pro tip: Many modern tools convert between formats instantly. Start with Markdown for rich formatting, then export to plain text when universal compatibility is needed.

Used in TNT development: Markdown spec files power the TNT rapid-development workflow — one filled-in spec file replaces a dozen copy-paste conventions. See Ask Copilot Entry #040 for the complete story.
