CSV viewer

Open a CSV file or paste text and see it as a table you can sort by column and search, without opening Excel. The separator is found for you, and files up to 20 MB open. It runs in your browser and your file is not sent anywhere.

This tool needs JavaScript. If you still see this after a few seconds, JavaScript is switched off in your browser or the page did not load completely: turn JavaScript on or reload the page.

How to use it

  1. Press "Open file" and choose a .csv file, or paste the text in the box. The table appears at once.
  2. Press a column heading to sort (again to reverse, once more to cancel). Type in "Search the table" to filter the rows.
  3. Press "Copy" to paste into a spreadsheet, or "Download" a CSV that is sorted and filtered.

Frequently asked questions

Thai text looks garbled when I open a CSV

The browser reads the file as UTF-8. A file from an older Excel may be saved in the computer's legacy encoding (Windows-874), which looks garbled. Open it in Excel and save it again as "CSV UTF-8 (Comma delimited)". The file downloaded from this tool has a BOM, so Excel reads Thai correctly.

Can it open big files?

Up to 20 MB (hundreds of thousands of rows). The table shows 200 rows at a time so the page stays quick; press "Show more" or "Show all". Sorting and searching work on every row, not only the ones in view.

What if the separator is wrong?

The tool guesses the separator from the first lines. If it guesses wrong (a file with one column, say), choose comma, semicolon, tab or pipe yourself.

Good to know

Your data stays on your device

Everything runs in your browser. What you type, paste or open is not sent to freesabai's servers or anyone else's, and is not kept in the browser: close the page and it is gone. The site only counts how many times this page was opened and how many times someone copied or saved a result (never what was pasted or the result, and you can switch the counting off in the footer; see the privacy policy).
