Why Split & Send
🔒 Private by design
Your Excel files never leave your browser. No uploads, no servers, no accounts, no data collection.
🎨 Keeps your formatting
Colors, borders, fonts, column widths and number formats are preserved in every split file.
✉️ Ready-to-send drafts
Each part comes with an .eml draft: right recipient, your message, the file already attached. Open, review, send.
How it works
Frequently asked questions
Is Split & Send free?
Yes, completely free — no account, no limits, no ads. If it saves you time, you can support the project with a small donation.
Is my data safe?
Everything runs locally in your browser. Your spreadsheet is never uploaded anywhere, which makes Split & Send suitable for confidential business data.
Which file formats are supported?
.xlsx (with original formatting preserved), plus .xls and .csv (split without formatting).
How do the email drafts work?
Each group gets a .eml file that opens in Outlook and other mail clients as an editable draft, with recipient, subject, message and attachment already in place.
Can it handle multiple sheets?
Yes. Split a single sheet, or all sheets at once — each with its own split column. Every group gets one Excel file containing all its matching sheets.
Free, independent, no ads
Split & Send is built and maintained by one person. If it saves you time, you can buy me a coffee.
