Find and Replace

The Find and Replace tool is a powerful text search and substitution utility that supports both plain text and regular expression patterns. With live match highlighting, you can see exactly what your search pattern matches before making any changes. This tool is essential for developers, writers, and data professionals who need precise text manipulation.

Step-by-Step Instructions

Step 1: Paste or type your text into the main input area at the top. This is the text that will be searched and modified.

Step 2: Enter your search term in the "Find" field. As you type, the preview area highlights all matches in yellow, and the match count updates in real-time.

Step 3: Enter your replacement text in the "Replace with" field. This is what each match will be replaced with. Leave it empty to delete matches.

Step 4: Configure your options: enable "Use regex" for pattern matching, "Case sensitive" for exact case matching, and "Replace all" to replace every occurrence or just the first one.

Step 5: Click "Replace" to perform the substitution. The result appears in the output area where you can copy it.

Using Regular Expressions

Regular expressions (regex) are powerful patterns for matching text. Common patterns include: \d+ matches one or more digits, \w+ matches word characters, [A-Z] matches uppercase letters, ^ matches the start of a line, and $ matches the end. You can combine these with quantifiers like * (zero or more), + (one or more), and ? (optional).

Capture groups using parentheses let you reference matched text in your replacement. For example, finding (\d3)-(\d4) and replacing with ($1) $2 transforms "555-1234" into "(555) 1234".

Common Use Cases

Data Cleaning: Remove unwanted characters, standardize formats, or fix common typos across large texts. Code Refactoring: Rename variables, update function calls, or modify patterns across source code. Content Editing: Replace outdated terms, fix formatting issues, or update references throughout documents.
