What this tool does to your file
The CSV becomes an Apple Numbers spreadsheet with each value in its own cell. The delimiter is sniffed rather than assumed: comma wins ties, but semicolon is accepted too, because Excel writes semicolon-delimited CSV in every locale whose decimal separator is a comma — Hungarian among them — and parsing such a file as comma-delimited yields one column holding each entire row as text. Numeric coercion is deliberately narrow, matching only a plain optionally-negative decimal, so leading-zero product codes and long identifiers stay as text instead of being silently converted. A file that turns out to be binary wearing a .csv extension is rejected rather than parsed into nonsense. CSV uploads are capped at 10 MB whatever your tier, because a dense CSV costs far more as cells than it did as bytes.
What happens to your files
- No account needed — Every tool works as a guest. Signing in raises the limits and keeps your files together, but nothing asks you to register before you get a result.
- It runs in your browser — There is nothing to install and nothing to keep up to date. Files travel to our servers over an encrypted connection, and come back the same way.
- Your files stay yours — Files and results stay in your account until you delete them. Files from a guest session that is never linked to an account are removed automatically after a period of inactivity.
- Size limits, stated up front — Up to 10 MB per file as a guest, and up to 25 MB signed in. You see the limit before you upload, not after.
