Frequently asked questions
Is my CSV uploaded?
No. The file is read locally by your browser and never sent anywhere.
Which delimiters are supported?
Comma, semicolon, tab, and pipe are detected automatically, and quoted fields with commas or line breaks are handled.
Can it open large files?
Yes. Rows are shown 100 at a time, so files with tens of thousands of rows stay responsive.
