Email Extractor
Find and lowercase ASCII email candidates
Paste text to find ASCII email candidates, lowercased in full, deduplicated, and sorted. This does not check delivery or open Excel files.
The full guide also includes pitfalls, worked examples, snippets, FAQs, and related tools for checking results or troubleshooting.
About this tool
Find email-like ASCII strings in pasted text, lowercase the whole address, and return a sorted unique list. Plus tags remain part of the address. The pattern does not implement every valid email syntax and may extract partial matches from malformed input. It does not open Excel or document files, decode HTML entities, look up DNS, or check mailbox existence or delivery.

INPUT
Contact Support@Example.COM and support@example.com.
Billing: billing+eu@example.org
Obfuscated: name [at] example [dot] com
OUTPUT
billing+eu@example.org
support@example.com
These are extracted candidates, not confirmed mailboxes. Original local-part casing is not preserved.Frequently Asked Questions
How are duplicates handled?
The entire matched address is lowercased before deduplication and sorting. Local-part case is therefore not preserved; keep the source if exact identity or provenance matters.
Are plus tags or dots removed?
No. billing+eu@example.org and billing@example.org remain different candidates. The tool does not apply provider-specific mailbox equivalence rules.
Can I upload a spreadsheet or extract obfuscated addresses?
No file reader is provided. Paste text copied from a spreadsheet if needed. Forms such as name [at] example [dot] com are not reconstructed, and internationalized or quoted-address syntax is not fully supported.
Does a match prove an address is valid or deliverable?
No. Pattern matching can include malformed or partial candidates. There are no DNS, mailbox, or delivery checks; even a separate syntax check does not prove delivery.
