Datavisly

Free Online CSV Viewer

Open a CSV file to view it as a clean, sortable table. Files are parsed entirely in your browser — nothing is uploaded to a server.

View and sort any CSV file in your browser

Datavisly's CSV viewer turns raw comma-separated data into a tidy, readable table in seconds. There's nothing to install and no account to create — just drop a file and start exploring. It's perfect for quickly inspecting an export from Excel, Google Sheets, a database, or an analytics tool without opening heavy software.

Because everything runs locally in your browser, your data stays completely private. The viewer handles quoted fields, values that contain commas, and other common formatting quirks, so your table looks right the first time.

How to view a CSV file

  1. Drag your .csv file onto the upload box, or click to choose one.
  2. The file is parsed instantly and shown as a table.
  3. Click any column header to sort the rows by that column.
  4. Click the header again to reverse the sort order.

Frequently asked questions

What is a CSV file?
CSV stands for Comma-Separated Values. It's a plain-text format where each line is a row and columns are separated by commas (or sometimes semicolons or tabs). Spreadsheets and databases like Excel, Google Sheets, and many apps export data as CSV.
How do I open a CSV file online?
Drag your .csv file onto the box above, or click it to choose a file from your device. Datavisly instantly parses the file and shows it as a readable, sortable table — no software to install and no account needed.
Is my CSV file uploaded to a server?
No. Your file is read and parsed entirely inside your own browser using JavaScript. It never leaves your device and is never sent to or stored on any server, so even sensitive data stays private.
Can I sort the data?
Yes. Click any column header to sort the rows by that column. Click again to reverse the order. Numeric columns are sorted as numbers and text columns alphabetically.
How large a file can it handle?
The viewer reads files of most sizes, and displays the first 5,000 rows for smooth performance. It supports quoted fields, commas inside values, and other common CSV edge cases.
Is it free?
Yes, the CSV viewer is completely free with no sign-up, no limits on the number of files, and no watermarks.
