Open a CSV, TSV or pipe-separated file, filter it and sort it column by column in a table.

Table
Click a column heading to sort by it, and click again to reverse the order. The file is read in the page, so it never leaves your computer. Very large files are shown up to the first five hundred rows.
History for this tool
The most recent data you entered in this tool, stored only in this browser.
Save what you type here, in this browser? Your work would go into this browser's local storage, so a refresh or a trip to another tool does not wipe it. You also get a short list of previous entries under the form, each one restorable with a click. Nothing is ever uploaded, and there is no account.
Being straight about the trade-off: anything kept there can be read by anyone who can use this browser profile, and by any script that later runs on this site. A tool page can hold a private key, a password or a signed token. Saving is convenient; it is not private.
About this tool
Drop in a CSV, TSV or pipe-separated file and read it as a table. The delimiter is guessed from the first line, but you can sort by any column, type in the filter box to narrow the rows, and see the shape of the file at a glance. The file is parsed in the page, so nothing is uploaded.
Questions
- How does it pick the delimiter?
- It counts commas, semicolons, tabs and pipes on the first non-empty line and uses whichever appears most. A file with a single column falls back to the comma.
- How large a file can it open?
- The whole file is parsed, but only the first five hundred rows are drawn to keep the page responsive. The row count in the corner always reflects the full file, not just what is shown.
- Does it read quoted fields?
- Yes. A field wrapped in double quotes may contain the delimiter, a newline or a doubled quote, and the viewer keeps it as one value rather than splitting it.
