Big CSV viewer

SQL · no upload

Excel gives up around a million rows. Drop the file here instead — it opens instantly, and you can filter it with real SQL. Works on files of several hundred MB because the data is streamed off your disk, not loaded into a web page.

🔒
Nothing is uploaded. DuckDB is compiled to WebAssembly and reads the file straight from your disk inside this tab. Close the tab and it is gone.
