CSV Viewer — Most CSV viewers are desktop apps: Excel, Numbers, LibreOffice. They work, but they require an install, an account (for the cloud versions), or a license. For a quick "what is in this file?" question, a browser-based viewer is faster.
CSV parsing and filtering happen entirely in your browser. Files are never uploaded.

What is csv viewer?
Most CSV viewers are desktop apps: Excel, Numbers, LibreOffice. They work, but they require an install, an account (for the cloud versions), or a license. For a quick "what is in this file?" question, a browser-based viewer is faster.
This viewer parses the CSV in your browser, shows it as a sortable, searchable table, and lets you filter, sort, and export the result. The file never leaves your device.
How to use it
-
Paste or drop a CSV
Drop a file onto the input area, click "Open file" to pick one, or just paste CSV text. The first row is treated as the header.
-
Read the stats
The summary cards show row count, column count, total cells, and the number of empty cells. Useful for a quick "how messy is this data?" check.
-
Filter and sort
Click any column header to sort by it (numeric sort when the values are numbers, alphabetic otherwise). Type in the search box to filter rows by any cell value.
-
Export the result
Download the filtered view as a CSV, or copy the whole thing as a JSON array. The export reflects the current sort and filter.
Examples
A small contacts list
Six rows, four columns, no missing values.
name,email,role,active Ada,[email protected],engineer,true Grace,[email protected],engineer,true
Result: A 6×4 table with sortable columns and a search box.
