Text processing and manipulation are core operations in software development, content management, and data analysis. This category covers essential text tools including case conversion (camelCase, snake_case, kebab-case, PascalCase), character escaping for different contexts (HTML, JavaScript, SQL), text diffing for code review and comparison, character encoding conversion, and text statistics. These tools are critical for code generation, API integration, content preparation, and text analysis. Understanding naming conventions across programming languages, escaping rules for different contexts, diff algorithms, and character encoding standards ensures reliable text processing and prevents security vulnerabilities. This guide covers text standards, escaping best practices, and common troubleshooting scenarios.
Convert text between different naming conventions: camelCase, snake_case, kebab-case, PascalCase, SCREAMING_SNAKE_CASE. Essential for code generation and style guide compliance.
Escape and unescape text for different contexts: HTML, XML, JavaScript, JSON, SQL, CSV. Prevents XSS attacks and syntax errors.
Compare two text blocks visually, highlighting additions, deletions, and changes. Useful for code review, version control, and content verification.
| Tool Type | Features & Use Cases |
|---|---|
| Case Converters | camelCase: first word lowercase (iPhone). PascalCase: first word uppercase (iPhone). snake_case: lowercase with underscores (python standard). SCREAMING_SNAKE_CASE: constants. kebab-case: CSS class names. |
| Character Escaping | HTML: < → <, & → &. JavaScript: ' → \', " → \". SQL: ' → '' (two quotes). CSV: " → "" (two quotes). Context-specific rules prevent injection. |
| Diff Algorithms | Line-by-line: shows changed lines. Character-by-character: shows exact character changes. Unified diff: standard format for patches. Essential for code review. |
| Text Statistics | Character count: includes/excludes spaces. Word count: useful for SEO and content management. Readability: Flesch-Kincaid, Gunning Fog indices. Sentiment analysis: positive/negative tone. |
| Regular Expression Tools | Pattern matching: find/replace operations. Validation: email, phone, URL formats. Extraction: pull data from text using capture groups. |
| String Utilities | Trim: remove leading/trailing whitespace. Reverse: flip string order. Remove duplicates: keep unique characters or lines. Shuffle: randomize string order. |
JavaScript/Java: camelCase for variables. Python: snake_case for variables. C#: PascalCase for properties. Constants: SCREAMING_SNAKE_CASE. Consistency prevents confusion and improves code readability.
HTML escape for web display, JavaScript escape for JS strings, SQL escape for queries, URL escape for parameters. Never trust user input, always escape. Use framework functions, not manual escaping.
Check character encoding before conversion. Validate text format before parsing. Use schema validation for structured text (XML, JSON).
Test with Unicode, emoji, RTL languages. Normalize text (NFC, NFD) for consistent comparison. Be aware of combining characters and zero-width spaces.
Always diff before committing code changes. Review exact character-level changes for critical code. Use semantic diffs for code review efficiency.
For large texts (>1MB), use streaming operations. Avoid creating intermediate strings. Use StringBuilder/StringBuffer for concatenation. Cache regex patterns.
