Plain Text: The Essential Guide for Writers and DevelopersPlain text—characters with no formatting, markup, or hidden metadata—might seem humble, even old-fashioned. Yet its simplicity powers much of modern writing, development, and long-term information storage. This guide explains what plain text is, why it still matters, how writers and developers can use it effectively, and practical workflows and tools to integrate plain-text habits into daily work.
What is plain text?
Plain text consists of readable characters encoded using character sets like ASCII or UTF-8. Unlike rich text or binary formats, plain text contains no styling (bold, italics), layout metadata, or embedded objects. Files are usually saved with extensions such as .txt, .md, .csv, .json, .xml, .yaml, and source-code extensions (.py, .js, .c).
Key fact: Plain text files are human-readable, portable, and have predictable behavior across platforms.
Why plain text still matters
- Durability and longevity: Plain text is future-proof. Plain text files are unlikely to become unreadable as software evolves because they rely on universally supported encodings.
- Portability: Any OS or editor can open plain text. This makes sharing and collaboration frictionless.
- Version control friendliness: Line-oriented formats work exceptionally well with Git and other VCS, enabling precise diffs and merges.
- Automation and tooling: Plain text is easy to parse and manipulate with scripts and command-line tools (sed, awk, jq).
- Privacy and transparency: No hidden metadata means fewer privacy surprises from embedded properties or proprietary wrappers.
- Minimal distractions: Writers benefit from focusing on content over presentation; developers benefit from focusing on logic rather than WYSIWYG quirks.
Plain text vs. rich text: tradeoffs
| Aspect | Plain Text | Rich Text |
|---|---|---|
| Readability | High across platforms | Dependent on software |
| Styling | None (separate formats like Markdown) | Built-in (fonts, layout) |
| File size | Typically smaller | Larger due to metadata |
| Version control | Excellent | Poorer diffs, merge conflicts |
| Ease of automation | Excellent | Difficult without converters |
| Accessibility | High (simple encodings) | Varies with format |
Common plain-text formats and when to use them
- .txt — Quick notes, simple logs.
- .md (Markdown) — Lightweight formatting for documentation, READMEs, blogs.
- .rst (reStructuredText) — Python docs and Sphinx projects.
- .csv — Tabular data interchange.
- .json, .yaml, .xml — Structured data exchange and configuration.
- Source code files (.py, .js, .c, .html, etc.) — Program logic, scripts, web assets.
Best practices for writers
- Write first, format later: Use plain text for drafting to get ideas down without layout concerns.
- Use Markdown for lightweight structure: headings, lists, links, emphasis—portable and readable.
- Use consistent file naming: lowercase, hyphens or underscores, dates in ISO format (YYYY-MM-DD).
- Keep paragraphs short and use line breaks thoughtfully: consider soft-wrapping vs. hard line breaks depending on your tools.
- Back up with Git or simple sync: track changes and recover earlier drafts easily.
- Avoid proprietary characters: stick to UTF-8 for widest compatibility.
Example filename convention: project-name/2025-09-01-first-draft.md
Best practices for developers
- Prefer UTF-8 encoding with a BOM avoided (unless required).
- Enforce consistent newline style across projects (.gitattributes to normalize CRLF/LF).
- Use code linters, formatters, and pre-commit hooks to keep plain-text sources consistent.
- Store configuration in plain-text formats (YAML, JSON) for transparency.
- Use meaningful, small commits for easy diffs and rollbacks.
- Prefer line-oriented logging for easier parsing by tools like grep, awk, and jq.
Sample .gitattributes snippet:
* text=auto eol=lf Tools and editors
- Cross-platform editors: VS Code, Sublime Text, Atom (deprecated but usable), Neovim, Emacs.
- Lightweight editors: Notepad++, nano, TextEdit (plain mode).
- CLI tools: sed, awk, grep, cut, sort, uniq, jq (JSON), yq (YAML).
- Note-taking/PKM: Obsidian, Logseq, Zettlr (use Markdown files stored as plain text).
- Conversion/preview: Pandoc for format conversion (Markdown ↔ DOCX/PDF/HTML).
Workflows: examples
Writers — Blog post workflow:
- Draft in Markdown locally or in a notes repo.
- Use Pandoc or a static site generator (Hugo, Jekyll) to build HTML/PDF.
- Commit drafts to Git; use branches for major revisions.
- Publish via CI that converts Markdown to the site.
Developers — Config + code workflow:
- Keep configuration in YAML/JSON stored in the repo.
- Validate config with CI (schema validation).
- Use pre-commit hooks to run linters and formatters on staged files.
- Use small commits and code reviews for changes.
Common pitfalls and how to avoid them
- Encoding mismatches: Always declare and use UTF-8.
- Hidden metadata from other tools: Avoid saving drafts in proprietary apps or export plain text before committing.
- Large binary blobs in repositories: Keep binaries out of VCS; use LFS or external storage.
- Over-reliance on a single editor’s features: Favor portable formats so collaborators aren’t locked into tools.
Security and privacy considerations
Plain text offers transparency but no built-in encryption. For sensitive content:
- Use end-to-end encryption tools (GPG, age) for storage and sharing.
- Use secure key management and avoid plaintext secrets in repos; prefer secret managers or encrypted files.
The future of plain text
Plain text will remain foundational. As tools grow smarter (AI-assisted editors, static site generators, rich real-time collaboration), plain text’s role as the interoperable, human-readable substrate will keep it central to both writing and software development.
Quick reference checklist
- Use UTF-8 encoding.
- Prefer Markdown for lightweight formatting.
- Normalize newlines and whitespace.
- Version-control plain-text files.
- Avoid secrets in plaintext repositories.
- Use simple, descriptive filenames and ISO dates.
Plain text is small, robust, and versatile — a low-friction medium that scales from a single note to large codebases and documentation ecosystems. Its restraint is its power: when you remove formatting and complexity, you make information easier to share, automate, and preserve.
