CSV Viewer FAQ
Is my file uploaded to a server?
No. The file is opened and rendered entirely in your browser. Nothing is uploaded or stored.
Which delimiters are supported?
Commas, semicolons, tabs, and pipes are detected automatically from the first line. Quoted fields, escaped quotes, and multi-line values are handled.
Can I view large CSV files?
Files up to 50 MB are read in the background so the page stays responsive. Rows are shown 100 per page in the table and 25 per page as cards.
Can I save a filtered version?
Yes. Search, sort, and hide columns, then choose Export to download exactly the rows and columns you are viewing as a new CSV file.
How do the readability settings work?
Adjust text size, line spacing, reading width, font, and color theme (paper, sepia, high contrast, or night). Only settings that affect the current view are shown, and your choices are remembered on this device.
