HIPAA Compliant Find & Replace

How to Use Find & Replace

This free online find and replace tool lets you search for text patterns and replace them across large documents entirely in your browser. With support for both plain text and regular expression (regex) search, case-sensitive matching, and real-time match highlighting, it's the fastest way to perform bulk text transformations without installing any software.

Step-by-Step

1. **Paste your text** into the main input area.

Enter your search term — Type the text or regex pattern you want to find.

Enter the replacement — Type what the matched text should be replaced with.

Choose your options — Toggle case sensitivity, enable regex mode, or select replace-all vs. replace-one.

Click Replace — View the result instantly with all replacements applied.

Features

Plain text search — Simple string matching for straightforward replacements.

Regex support — Full JavaScript regular expression syntax for complex pattern matching.

Case-sensitive toggle — Control whether the search respects letter casing.

Replace all or one-by-one — Replace every match at once or step through matches individually for selective replacement.

Match highlighting — See all matches highlighted in the input text before committing to the replacement.

Match count — Know exactly how many matches were found before replacing.

100% client-side — Your text is processed in the browser. No data is transmitted to any server.

Common Use Cases

Bulk Variable Renaming — Rename a variable or function across a code file using regex to match word boundaries: \boldName\b → newName.

Log File Cleanup — Strip timestamps, IP addresses, or session IDs from log files before sharing them with teammates or posting in issue trackers.

Data Format Conversion — Convert date formats (MM/DD/YYYY to YYYY-MM-DD), phone number formats, or CSV delimiters using regex capture groups.

Content Migration — Bulk-update URLs, file paths, or domain names when migrating websites or documentation to a new host.

Markdown and HTML Editing — Convert Markdown links to HTML anchors (or vice versa) using regex pattern matching and replacement groups.

Tips for Power Users

- Use regex capture groups (...) in your search pattern and reference them in the replacement with $1, $2, etc. for powerful transformations.

- The \b word boundary anchor in regex prevents partial matches — \bcat\b matches "cat" but not "category".

- Enable the global flag to replace all occurrences rather than just the first match.

- For CSV transformations, use regex to match comma-separated values and restructure columns.

- Preview the match count before replacing to ensure your pattern isn't matching unintended text.

Why Use this HIPAA Compliant utility?

Unlike desktop text editors that require opening files locally, this HIPAA Compliant utility works with pasted text directly in your browser. It supports the full JavaScript regex engine, giving you the same power as String.prototype.replace() with a visual interface. No data is uploaded, no accounts are needed, and it works with text of any length — making it perfect for quick find-and-replace operations on the go.
