Frequently Asked Questions
Does this support regular expressions? ▼
Yes. Enable regex mode to use powerful pattern matching. For example, \d+ matches any sequence of digits, and (\w+)@(\w+) captures email-like patterns. Regex replacement supports backreferences like $1 and $2 to reuse captured groups in the replacement text.
What is the difference between case-sensitive and case-insensitive search? ▼
Case-sensitive search matches the exact letter casing: searching for "Hello" will not match "hello" or "HELLO". Case-insensitive search ignores casing and matches all variations. Most text editors default to case-insensitive unless you specifically enable it.
Can I replace with nothing to delete text? ▼
Yes. Leave the replacement field empty to delete all matches. This is useful for removing unwanted characters, extra spaces, HTML tags, or specific words from your text.
What is whole-word matching? ▼
Whole-word matching ensures the search term is matched only as a complete word, not as part of a larger word. Searching for "cat" with whole-word matching will match "the cat sat" but will not match "category" or "concatenate".
How many replacements can this tool handle? ▼
Since the tool runs in your browser using JavaScript, it can handle documents with tens of thousands of lines efficiently. For extremely large files (10MB+), performance depends on your device and browser, but most practical use cases run instantly.
Is my text stored? ▼
