Text Formatting Tools Complete Guide
Case conversion, analysis, encoding, and cleanup — what each tool does and when to reach for it.
What these tools cover
Text tools here fall into a few buckets: case styles (title, sentence, camelCase, snake_case), counting and readability, encoding (Base64, URL, HTML), cleanup (spaces, duplicates, tags), and a few creative transforms. Pick the one that matches the job instead of chaining five half-fits.
Case conversion
Upper / lower / title / sentence
All caps for short labels. Lower for consistency. Title for headings. Sentence for body copy.
| Format | Use for | Example |
|---|---|---|
| Title Case | Headings, titles | Hello World |
| Sentence case | Body text | Hello world |
| camelCase | JS/Java variables | helloWorld |
| kebab-case | URLs, CSS classes | hello-world |
| snake_case | Python, Ruby | hello_world |
| PascalCase | C# / Go types | HelloWorld |
Text analysis
- Counts: words, characters, sentences, paragraphs — for limits and drafts. Word count, character count.
- Readability: Flesch and grade-level scores. Readability scorer.
- Keywords: density and word frequency. Density, frequency.
- Diff / replace: compare versions or swap phrases. Diff, find/replace.
Encoding
- Base64 — binary as text (data URLs, attachments).
- URL encode and slug generator — safe query strings and paths.
- HTML entities, strip tags.
- Binary, Unicode, ROT13.
Cleaning
- Whitespace: extra spaces, trim lines, empty lines.
- Content: remove numbers, punctuation, or duplicates; keep letters only.
- Structure: sort, chunk, line numbers, reflow.
