Does my customer list get uploaded?

No. The file is read by your browser and never sent anywhere — there is no server in this tool at all. That is why it is free and why there is no row limit to buy your way past.

Can I send the messages from here?

No, and you should be wary of anything that claims to. Automated bulk sending violates WhatsApp's terms and gets numbers banned. This builds the links; you open them, or you paste them into a tool you already trust.

Why is one of my messages flagged as too long?

Because the limit is measured on the encoded URL, not on characters. The same message inflates about 1.4× in English and over 6× in Hindi, so a message that is fine in one language can silently break the link in another. The meter shows the real number per row.

What you actually get

It will not quietly mangle your numbers

The best-known free bulk tool splits each row on a hyphen, so 202-555-0188 becomes the number 5550188. It imports cleanly and it is wrong. This one splits on commas, tabs and semicolons only.

You choose the columns

We suggest a mapping and let you change it. A tool that guesses which column is the phone number is right until it meets a file with two of them.

The failures come back usable

Download the rows that failed, each with its spreadsheet line number and a reason like “too short for this country” — not a count and a shrug.
