Frequently asked questions

What if my files have different columns?

Matching headings are combined; columns that exist only in some files are added, left empty for the others.

Is Merge Excel & CSV free?

Yes. Merge Excel & CSV on DocEpic is free, with no sign-up, no watermark and no limit on how often you use it. The site is supported by ads.

Are my files safe with Merge Excel & CSV?

Yes. Merge Excel & CSV usually runs in your web browser, so the file never leaves your device. Files your browser can't handle well — such as HEIC photos in browsers other than Safari, or very large files — are sent over an encrypted connection and processed in our server's memory only, never written to disk. The result screen tells you which happened.

Do I need to install any software?

No. Merge Excel & CSV works in any modern browser on Windows, macOS, Linux, Android and iPhone.

Is there a file size limit?

Files up to 30 MB each can be processed.
