About CSV Viewer
Not everyone has Excel, and opening a CSV in it can mangle leading zeros, long numbers and dates. This viewer shows the file exactly as it is, as a table with a sticky header row. The separator is detected automatically, whether commas, semicolons, tabs or pipes, and quoted values with commas or line breaks are handled correctly. Click a column header to sort, type in the filter box to find rows, and download just the filtered, sorted rows as a new CSV.

Questions
Does it change my data like Excel can?
No. Values are shown exactly as text, so leading zeros, long IDs and dates stay as they are.
How big a file can it open?
Files with hundreds of thousands of rows work; the table shows the first 2,000 matching rows, and the download includes all of them.
Can I edit cells?
Not in the table. Edit the text on the left, and the table updates as you type.
Is my file uploaded?
No. The CSV is read in your browser.
