The same list, shaped for any destination

Half of email-list work is not extraction or cleaning — it is reshaping. Your CRM exports one-per-line, the newsletter platform wants CSV, mail merge needs semicolons, and your automation script expects JSON. The Email Formatter switches between all of them instantly, locally, without opening a spreadsheet.

Deduplication runs before formatting so every output shape starts from a clean unique set. Choose your target layout from the dropdown and the result panel re-renders on the spot; copy it to your clipboard or download it in the matching file format (.txt, .csv, or .json).

For heavier structural transformations — nested records, custom fields per address — step up to the Email Converter, which builds full CSV rows and JSON objects from your list.

A text email formatter for every workflow

The formatter doubles as a general-purpose text email formatter: bring a block of prose riddled with addresses and leave with exactly the layout your destination expects. Numbered lists make manual review easy; semicolon output drops straight into Outlook mail-merge fields; one-per-line is the lingua franca of bulk senders and CRM importers.

Everything about the output is predictable — stable ordering options (alphabetical or original), optional lowercasing for consistent dedupe-safe data, and zero hidden transformations. What you see in the result panel is byte-for-byte what you copy or download.

And because formatting is local, it is safe for confidential lists: candidate pools, client contacts, patient communication rosters — none of them ever leave your machine to be reshaped.

FAQ

Email Formatter questions

Which formats can I convert my list into?

One-per-line plain text, comma-separated, semicolon-separated (the format many European tools expect), space-separated, a numbered human-readable list, CSV with a header row, and JSON arrays.

When do I need a specific separator?

Mail-merge fields in Outlook often want semicolons, bulk-sending platforms usually import one-per-line or CSV, spreadsheets prefer CSV with headers, and scripts consume JSON. The formatter covers all of these without touching a spreadsheet formula.

Does formatting change the addresses themselves?

No — only their arrangement and separators. Duplicates are removed first so no format ever contains repeats; addresses keep their original casing unless you enable lowercasing.

Is the formatted output uploaded anywhere?

No. Formatting happens in your browser like every other tool here. Copy results to your clipboard or download them as .txt, .csv, or .json.
