Text Replacer

Overview

Text Replace supports both plain-text replacement and regex-based replacement for batch edits, formatting cleanup, and data masking. It also supports file input, copy, and download.

Core Features

• Plain find/replace with case and replace-all controls.
• Regex replacement with g/i/m/s/u/y flags.
• File import for common text formats (.txt/.csv/.json/.xml/.log/.md).
• Live stats: match count, replace count, input/output length.

Common Use Cases

• Data cleaning and standardization.
• Code refactoring and bulk renaming.
• Document processing and marker replacement.

Regex Examples

• Email: \b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\.[A-Z|a-z]{2,}\b
• Phone: 1[3-9]\d{9}
• Number: \d+
• Whitespace: \s+

Flag Reference

• g: global replace for all matches.
• i: case-insensitive matching.
• m: multiline anchors for ^ and $.
• s: dot matches newline.
• u: Unicode-aware processing.
• y: sticky matching at lastIndex.

Notes

• Test regex on small input first.
• Large files take longer; keep size within 10MB when possible.
• All processing runs locally in the browser.
