Frequently Asked Questions
Why does Excel mangle my CSV?
Two usual reasons: it assumes the system codepage without a UTF-8 byte order mark, so accents break; and it converts anything that looks like a number, destroying leading zeros in postcodes and IDs. This viewer does neither.
How are commas inside values handled?
Correctly, when the field is quoted. "Smith, Ada",42 parses as two fields. Doubled quotes inside a quoted field are treated as an escaped quote, per RFC 4180.
Is my CSV uploaded?
No. The file is read and parsed in your browser, which matters because CSV exports so often contain customer data, financial records or personal information.
How large a file can it open?
Files of tens of megabytes work comfortably on a desktop browser. Very large files are limited by memory, since the whole table is held in the page.
Files are read directly from your device by the browser and processed in this page. Nothing is uploaded, which is why there is no progress bar and why large files are handled instantly.
