FAQ

Does CSV Merge upload my data?

Most main-site tools process input locally in the browser. Website diagnostic tools that request public URLs explain the remote request scope in the tool UI.

Can I use CSV Merge on mobile?

Tool pages use responsive layouts for phone, tablet, and desktop. Large file processing still depends on device memory and browser limits.

Can I download or copy the CSV Merge result?

Migrated tools provide copy, download, or direct result views in the output area depending on the tool type.
