Opening a CSV in a spreadsheet to look at it is a slow, slightly dangerous habit. Excel will helpfully turn your product codes into dates, drop leading zeros from postcodes and offer to save changes you never made.

What CSV Viewer & Sorter does

Renders a CSV or TSV as a readable table with a live row filter, so you can inspect a file without opening anything that might alter it.

Nothing is modified and nothing is uploaded — the file is parsed in the browser tab and forgotten when you close it.

What it handles

FormatsCSV and TSV, from a file or pasted in
Quoted fieldsHandled — commas inside quotes do not split a column
Header rowTreated as the first row and used for the column names
FilterMatches across all columns, live as you type
Leading zerosPreserved — nothing is coerced to a number or a date
ProcessingIn the browser; the file is never uploaded

Detailed steps

  1. Choose a file, or paste the rows straight in.
  2. Scan the header row first — a shifted column is easier to spot there than anywhere else.
  3. Use the filter to find rows rather than scrolling.
  4. Nothing is saved. The file on disk is untouched.

Worth knowing

This is the safest way to look at an export before it goes anywhere near a spreadsheet. Excel silently reformats on open — 007 becomes 7, 3-4 becomes 3 April, and a long product code becomes scientific notation — and the damage is invisible until someone downstream asks why the postcodes are wrong. Viewing first tells you what is actually in the file, as opposed to what a spreadsheet decided it meant.

Frequently Asked Questions

Why not just open it in Excel?

Because Excel changes things on the way in. Leading zeros are stripped, anything resembling a date is converted to one, long numeric codes become scientific notation, and none of it is announced. If you then save, the altered version is what persists — which is why viewing a file and editing a file are worth keeping separate.

Does it handle commas inside a field?

Yes, provided the field is quoted, which is the standard CSV convention. "Smith, John" stays as one cell rather than splitting into two. If a file was generated without quoting its commas it is genuinely ambiguous, and no parser can reliably recover it.

Is my file uploaded anywhere?

No. It is read and parsed inside the browser tab on your own machine, which is why there is no upload wait and why it works with the network disconnected. Nothing is stored and nothing is transmitted, so it is safe for exports containing customer or financial data.

How large a file can it handle?

It renders the whole table into the page, so very large exports — hundreds of thousands of rows — will make the browser sluggish before anything breaks. For files at that scale, filtering or splitting the export before viewing is more comfortable than asking a page to draw a million cells.

Is CSV Viewer & Sorter free?

Yes. The Vootkit free plan includes 5 tool runs a day. Upgrade to Vootkit Pro for unlimited daily use, an ad-free workspace and saved workflows.

Are my files uploaded?

No. CSV Viewer & Sorter runs entirely in your browser — your file is processed on your own device and never sent to a server. There is nothing for us to store or delete.

Do I need to install anything?

No. CSV Viewer & Sorter works in any modern browser on desktop, tablet or phone. Open the page and start.

How often can I use it? Is there a daily limit?

On the free plan you get 5 tool runs a day. When you reach the limit you'll see a prompt to upgrade, and it resets the next day. Vootkit Pro removes the cap entirely for unlimited daily use.

This tool processes everything locally in your browser. You can disconnect from the internet after the page loads and it will still work.
