Load a CSV file or paste the text, then click any column heading to sort and type in the search box to filter. Row and column counts update as you go.
No. The file is read with the browser's FileReader API and parsed in memory on your own machine. Nothing is sent over the network, which means you can safely open exports containing customer records, salaries or financial detail.
The parser handles quoted fields, commas and line breaks inside quotes, doubled quotes as an escape, and both CRLF and LF line endings. It also auto-detects whether your delimiter is a comma, tab, semicolon or pipe and whether the first row is a header.
Only the first block of rows is rendered so the page stays responsive, and a notice tells you how many rows the file actually contains. Sorting and searching still run over the complete dataset, not just the visible page.
