How to Use Find & Replace
Enter your text in the main area, type what you want to find in the "Find" field, type the replacement in the "Replace with" field, and click Replace All. The tool highlights all matches and performs the replacement instantly.
Advanced Options
Case Sensitive: When enabled, "Hello" and "hello" are treated as different strings. When disabled, both will match the search term "hello".
Regex Mode: Enables regular expression patterns for powerful, pattern-based searching. For example, \d+ matches any sequence of digits, \b\w+@\w+\.\w+\b matches email addresses, and ^ matches the start of each line.
