UUID Extractor

Extract UUIDs/GUIDs from any text — logs, source code, config files, and more. Paste your text and all identifiers are auto-detected, deduplicated, and ready to copy in 10 formats.

Extractor

How It Works

This tool scans your pasted text for UUID/GUID patterns in standard hyphenated 8-4-4-4-12 format (e.g. 550e8400-e29b-41d4-a716-446655440000), hyphenless 32-character hex format (e.g. 550e8400e29b41d4a716446655440000), and C-style 0x-prefixed byte sequences (e.g. ByteArray and DEFINE_GUID macro output). It automatically:

• Detects all UUIDs regardless of case or surrounding text
• Deduplicates by normalising to lowercase
• Formats them in 10 output formats with optional decorators (quotes, suffixes, case)

No data is sent to any server — all processing happens in your browser.

Common Use Cases

• Log analysis: Extract all GUIDs from server logs or crash dumps
• Code review: Find and convert GUIDs scattered across source files
• Database debugging: Pull GUIDs from SQL queries or result sets
• Config auditing: Verify GUIDs in .NET config files, COM registrations, or registry exports

Supported Output Formats

Identical to the UUID Generator — 10 formats including Standard, Hyphenless, Braces, URN, ByteArray, C++ Macro, C# Struct, Base64, Base64URL (RFC 7515), and URL Encoded.

FAQ

Does it detect GUIDs in any case? Yes — uppercase, lowercase, or mixed case are all detected and normalised to lowercase.

Can it extract GUIDs without hyphens? Yes — it detects standard hyphenated, hyphenless 32-character hex, and C-style 0x-prefixed byte sequences (ByteArray, DEFINE_GUID).

Can it extract GUIDs from C/C++ source code? Yes — it recognises 0x-prefixed byte runs such as { 0x55, 0x0E, ... } and DEFINE_GUID(...) macro output, reconstructing the UUID from the byte values.

Is my text sent to a server? No. All extraction and formatting happens entirely in your browser. No data leaves your device.
