Can I use regex patterns for find and replace?

This tool uses exact text matching, not regex patterns. For regex-based find and replace, use the Regex Tester tool which supports regex patterns and replacements. The Find and Replace tool is designed for simple, exact text matching.

What's the difference between case-sensitive and case-insensitive?

Case-sensitive matches text with exact capitalization ('Hello' only matches 'Hello', not 'hello'). Case-insensitive matches regardless of capitalization ('Hello' matches 'hello', 'HELLO', etc.). Enable case-sensitive if you want exact case matching.

What does 'Whole word' matching do?

Whole word matching only matches complete words, not parts of words. For example, finding 'cat' with whole word enabled matches 'cat' but not 'category' or 'scatter'. This prevents accidental partial matches. Disable whole word if you want to match text anywhere, even within other words.

Can I replace one occurrence at a time instead of all?

Currently, the tool replaces all occurrences at once. For one-at-a-time replacement, you would need to process the text multiple times, finding and replacing one occurrence each time. Desktop text editors typically offer one-at-a-time replacement with 'Find Next' functionality.

Will special characters in find text cause issues?

Special characters are treated as literal text in find and replace. For example, finding '.' will match a period character. If you need to find special regex characters literally, they work as-is in this tool (unlike regex where they need escaping). The tool uses simple text matching, not regex.

When to Use This Tool

Use this when:

You need to find and replace email addresses or URLs throughout a document
You want to replace placeholder text with actual content in templates
You're updating product names or brand names across multiple documents
You need to fix common typos or spelling errors in bulk text editing
You want to replace formatting codes or markup with different syntax
You're refactoring code and need to rename variables or functions across files
You need to standardize terminology or naming conventions in documents

Don't use this if:

You need to process very large texts (over 1 million characters may process slowly)
You require complex regex patterns with advanced features (use Regex Tester tool for complex patterns)
You want to replace text in binary files or non-text content (this tool only works with text)
You need to replace text across multiple files simultaneously (use desktop text editors)
You require conditional replacements or complex replacement logic (use specialized tools)

What is a Find and Replace Tool?

A find and replace tool searches for specific text patterns and replaces them with new text across your entire content. Our tool handles all operations in your browser — your text data stays completely private.

Find and replace is one of the most fundamental text editing operations: updating variable names in code, replacing outdated information in documents, standardizing formatting across content, bulk-editing CSV data, and performing text transformations that would be tedious to do manually.

This tool is valuable for content writers updating repeated terms across long documents, developers refactoring code without IDE access, data analysts cleaning and transforming text data, translators performing batch terminology updates, and anyone who needs to make systematic text changes across large content blocks.

Compared to text editor find-and-replace (which works on one file at a time), spreadsheet SUBSTITUTE functions (which require cell formulas), or command-line tools like sed (which require regex knowledge and vary between operating systems), PureXio provides a simple, visual find-and-replace interface with powerful options.

The tool supports plain text and regular expression search, case-sensitive and case-insensitive matching, whole-word matching, replacement preview before applying changes, a count of matches found, and step-through mode to review each replacement individually. The original text is preserved until you confirm the replacements.

Best for: finding and replacing text with plain text or regex patterns. Case-sensitive, whole-word, and regex modes. Preview before applying. Fully private.

How to Find and Replace Text

Paste your text into the input field. Text is ready for find and replace operations

Enter text to find and replacement text. Enable 'Case sensitive' if you want exact case matching, or 'Whole words' if you want to match complete words only

Click 'Find and Replace' to replace all occurrences (or one at a time if 'Replace All' is disabled). Preview shows replacement count and updated text

Common Use Cases

Find and replace email addresses or URLs throughout a document

Replace placeholder text (e.g., '{{COMPANY_NAME}}') with actual content in templates

Update product names or brand names across multiple documents

Fix common typos or spelling errors in bulk text editing (e.g., 'teh' → 'the')

Replace formatting codes or markup with different syntax

Rename variables or functions in code files during refactoring

Standardize terminology or naming conventions across documents

Limitations & Constraints

Very long texts (>1 million characters) may process slowly—consider splitting into smaller sections

Regex patterns are not directly supported—use exact text matching (use Regex Tester tool for regex)

Replacements are case-sensitive by default unless case-insensitive option is enabled

Whole word matching may miss words with punctuation attached (e.g., 'word.' won't match 'word' with whole word option)

Large number of replacements (>10,000) may take time to process

Troubleshooting

Find and replace not working or no matches found

Solution: Check case sensitivity setting—'Hello' won't match 'hello' unless case-insensitive is enabled. Verify the text to find is exactly as it appears in your text (including spaces, punctuation). Try without 'Whole word' option first to see if that's preventing matches. Prevention: Copy the exact text you want to find from your document to ensure it matches.

Replaced wrong text or replaced more than intended

Solution: Whole word option may not work if words have punctuation attached. Disable whole word matching, or be more specific with find text. If you're replacing common words, use whole word option to avoid partial matches. Review the match count before confirming replacement. Prevention: Test find and replace on a small sample first before processing large text.

Processing is slow or browser becomes unresponsive

Solution: Very long texts or many replacements process slowly. Split text into smaller sections and process separately, or wait for processing to complete. Close other browser tabs to free up resources. For extremely long texts, use desktop text editors. Prevention: Process text in smaller sections if it's very long.

Need regex patterns for complex find and replace

Solution: This tool uses exact text matching. For regex patterns, use the Regex Tester tool which supports regex find and replace, or use text editors with regex support. The Find and Replace tool is designed for simple text matching. Prevention: Use Regex Tester tool for regex-based find and replace operations.

Want to undo replacement or revert changes

Solution: Replacements are permanent once processed. Keep the original text in a separate file, or use browser undo (Ctrl+Z) immediately after replacement if you haven't made other changes. The tool doesn't have an undo feature, so save original text before processing. Prevention: Keep a backup of original text before making replacements.
