Extract MAC Addresses
Extract MAC addresses from pasted network logs, inventory exports, DHCP notes, and support tickets into a clean one-address-per-line list.
0 / 30,000 characters. No upload, storage, or account required.
Common MAC address extraction workflows
Use MAC address extraction when device identifiers are mixed into support notes, inventory exports, DHCP output, or copied network diagnostics.
Filter noisy exports
Use Filter Lines first when only rows containing device names, vendors, or subnets should be reviewed.
Pair with IP extraction
Use Extract IP Addresses or Extract IPv6 Addresses when logs include network addresses too.
Prepare clean lists
Finish with Sort Lines or Remove Duplicate Lines when the list needs final cleanup.
What this tool does
Extract MAC Addresses finds colon-separated and hyphen-separated MAC addresses in pasted text, can normalize separators to lowercase colon format, remove duplicates, and show source-line context locally in your browser.
Common use cases
Extract MAC addresses from pasted network logs, inventory exports, DHCP rows, and support notes for troubleshooting or clean list review.
Use Extract MAC Addresses when you are working with copied API payloads, logs, encoded values, config snippets, identifiers, or debugging data and need a quick browser-local check before pasting the result into docs, tickets, tests, or another developer tool.
How to use it
- Paste device inventory rows, DHCP logs, switch notes, support tickets, or copied network output that contains MAC addresses.
- Choose whether duplicate addresses should be removed and whether output should be normalized to lowercase colon-separated format.
- Copy the clean MAC address list for inventory review, troubleshooting notes, spreadsheet cleanup, or QA handoffs.
Example workflow
Copy a small payload or encoded value from an API response, request URL, log line, or config file. Run the focused check here, confirm the output is readable, then continue with related developer data tools such as validation, formatting, decoding, timestamp conversion, or CSV/JSON conversion.
Privacy note
MAC address extraction runs locally in your browser. ClearUtils does not upload, store, fetch, crawl, or log the text or addresses you paste.
FAQ
Does Extract MAC Addresses upload my network notes?
No. MAC extraction runs locally in your browser and does not upload, store, fetch, or log pasted text.
What MAC address formats are supported?
It finds common colon-separated and hyphen-separated MAC addresses, such as 00:1A:2B:3C:4D:5E and 00-1A-2B-3C-4D-5E.
Can it normalize MAC addresses?
Yes. Keep normalization enabled to convert hyphen-separated or uppercase addresses into lowercase colon-separated output.
