Complete Guide to Prompt Formatting
How to Use This Tool
The Prompt Formatter helps you clean and standardize AI prompts for consistent formatting across your applications. Follow these steps:
Paste Your Prompt
Enter or paste your prompt text in the input area. You can also click "Load Sample" to see an example of messy formatting that needs cleaning.
Select Formatting Options
Choose the cleaning and transformation options you need: remove extra spaces, normalize quotes, apply case transformations, set word wrap width, or enable code escaping options.
Click Format Prompt
Press the "Format Prompt" button to apply all selected transformations. The result appears in the output panel.
Copy or Download
Use the copy button to copy the formatted prompt to your clipboard, or download it as a text file for later use.
Why Format Prompts?
Consistent prompt formatting improves AI responses and reduces token usage. Prompts with inconsistent spacing, mixed quote styles, or unnecessary whitespace can lead to:
- • Wasted tokens: Extra spaces and formatting consume tokens without adding value.
- • Inconsistent behavior: Subtle formatting differences can affect model interpretation.
- • Code integration issues: Special characters can break JSON parsing or string literals.
- • Maintenance difficulties: Messy prompts are harder to read and update.
Formatting Options Explained
| Option | What It Does | When to Use |
|---|---|---|
| Remove extra spaces | Collapses multiple consecutive spaces into one | Almost always |
| Trim line whitespace | Removes leading/trailing spaces from each line | Clean up copy-pasted text |
| Remove line breaks | Converts multi-line to single line | API requests, compact format |
| Normalize quotes | Converts smart quotes to straight quotes | Text from Word/docs |
| Word wrap | Wraps text at specified column width | Readability, terminal display |
| Escape for JSON | Makes string safe for JSON embedding | API integrations |
| Escape for Python | Wraps in Python string literal | Python code embedding |
Case Transformation Options
lowercase
Converts all characters to lowercase.
input: "Hello World" → "hello world"
UPPERCASE
Converts all characters to uppercase.
input: "Hello World" → "HELLO WORLD"
Title Case
Capitalizes the first letter of each word.
input: "hello world" → "Hello World"
Sentence case
Capitalizes first letter after sentence endings.
input: "hello. world" → "Hello. World"
Code Escaping for API Integration
When embedding prompts in code, special characters must be escaped to avoid syntax errors. This tool handles the most common escaping scenarios:
JSON Escaping
Wraps the prompt in quotes and escapes special characters for use in JSON API requests:
Input: You are a "helpful" assistant.
Output: "You are a \"helpful\" assistant."
Python String Escaping
Escapes the prompt for use in Python string literals:
Input: Line 1
Line 2
Output: "Line 1\nLine 2"
Best Practices for Prompt Formatting
Formatting Guidelines
- Use consistent spacing: Single spaces between words, no trailing whitespace.
- Prefer straight quotes: Use standard ASCII quotes (" and ') for better compatibility.
- Keep line breaks intentional: Only use line breaks where they add clarity or structure.
- Escape before embedding: Always escape prompts when embedding in code.
- Version your prompts: Store formatted prompts in version control for tracking changes.
Common Formatting Problems
Issues This Tool Fixes
- Smart quotes from Word: Documents often use curly quotes that break code.
- Invisible characters: Copy-pasting can introduce hidden whitespace characters.
- Inconsistent indentation: Mixed tabs and spaces cause formatting issues.
- Multiple spaces: Extra spaces waste tokens and look unprofessional.
- Trailing whitespace: Invisible spaces at line ends can cause problems.
Token Optimization
Proper formatting can significantly reduce token usage. Consider these statistics:
- • Removing double spaces can save 5-10% of tokens in poorly formatted prompts.
- • Trimming whitespace typically saves 1-3% of tokens.
- • Converting to single-line format is most token-efficient for simple prompts.
Use the character and token counters at the bottom of each text area to monitor the impact of your formatting choices.
