CSV viewer

Drop a CSV, TSV or TXT file and it opens as a table with the header row on top. Type in the search box to find rows containing a value, and click a column header to sort by it. The delimiter is detected automatically.

The viewer is built to stay responsive with big files, including ones with hundreds of thousands of rows. Excel stops at 1,048,576 rows and can be slow long before that; a viewer is often the quickest way to check what's in a big export. The real limit is your device's memory.

Nothing in the file is changed. To fix problems you spot, like blank rows, stray spaces or duplicates, use the CSV cleaner. To work with the data in a spreadsheet, convert it with CSV to Excel; to break a huge file into parts, use Split CSV.

Exports you just want to peek at, from bank statements to user lists, are opened locally without an upload. The work happens in your browser, so nothing is uploaded and nothing is stored on a server. Once the page has loaded it keeps working offline, and it's free, with no sign-up and no watermark.
