This is a test. Here is another sentence.

Explanation

The sentence case converter capitalizes only the first letter of each sentence, making text natural and readable.

How This Tool Works

Paste or type any text into the input area, then click the Convert to Sentence Case button. The tool lowercases everything, then capitalizes the first letter of each sentence based on punctuation.

Input

Any text you paste or type—including ALL CAPS or inconsistent formatting.

Processing

The tool lowercases text then capitalizes letters after sentence endings (.!?).

Output

Naturally formatted text with proper sentence capitalization.

When to Use This Tool

•When you need to fix text that was typed in all caps or has inconsistent capitalization throughout.
•When preparing body content, paragraphs, or any text meant for natural reading.
•When formatting pasted content from various sources into consistent, professional sentence structure.

Common Mistakes

•
Forgetting to check proper nouns
Names, places, and brands need manual capitalization after conversion.
•
Using sentence case for headlines
Headlines often require title case. Check your style guide for heading formats.
•
Not reviewing acronyms
Terms like NASA or USA need to stay uppercase. Review and fix acronyms after converting.

Frequently Asked Questions

Common questions about this tool answered.

Sentence case capitalizes only the first letter of the first word in a sentence and any proper nouns. The rest remains lowercase. For example: 'The quick brown fox jumps over the lazy dog.'

Use sentence case for regular paragraphs, email body text, social media posts, subheadings in some style guides, and any text meant to be read naturally. It's the most readable format for longer content.

Title case capitalizes the first letter of every word (The Quick Brown Fox), while sentence case only capitalizes the first word of sentences and proper nouns (The quick brown fox). Sentence case is more natural for body text.

This tool capitalizes the first letter after sentence-ending punctuation (.!?) and the beginning of text. It does not automatically detect proper nouns—you may need to manually capitalize names and places.
