Overview

What is a CSV viewer?

A CSV file is just plain text — commas and line breaks standing in for the rows and columns of a table — which makes it easy to generate but genuinely uncomfortable to read directly. A CSV viewer parses that raw text and renders it as an actual table, with headers, aligned columns, and the ability to search across every row, so spotting a specific record doesn't mean scrolling through unformatted text.

This one accepts a CSV file dropped or uploaded directly, or CSV text pasted into a box, and handles quoted fields, alternate delimiters, and files with or without a header row.

How to use it

1Drop a CSV file, or paste CSV data directly
2Set the delimiter and whether the first row is a header
3Browse the rendered table
4Search to filter down to matching rows

How parsing and search work

The parser respects quoted fields, including ones that contain the delimiter itself or an escaped quote character, so a CSV exported from a spreadsheet renders correctly even when a value has an embedded comma. With "Has headers" on, the first row becomes the table's column names; with it off, every row is treated as data and generic column numbers are used instead. The search box filters rows by checking every cell for a match, so a search term matches regardless of which column it appears in.

Why this runs entirely in your browser

CSV files often contain real customer or business records, so nothing is uploaded. Parsing, rendering, and search all run in JavaScript locally in the tab, which means it keeps working offline once the page has loaded and nothing dropped or pasted into it persists after the tab is closed.

Common uses

Quickly checking the contents of a CSV export before importing it somewhere else, searching a large export for a specific record without opening a spreadsheet program, or verifying that a file's delimiter and header row are what a script expects before processing it further.

Frequently asked questions

A few things people usually want to know before trusting the numbers.

Yes, as long as the field is properly quoted in the source file — the parser respects quoted values, including ones containing the chosen delimiter.

When on, the first row is used as the table's column names. When off, every row — including the first — is treated as data, and generic column numbers are used instead.

It filters rows by checking every cell in each row for a match, so a search term is found regardless of which column it's in.

The table renders up to 500 matching rows at a time for performance — the exact count of matching rows is always shown above the table.

No. All parsing and viewing happens locally in your browser. Nothing dropped, pasted, or uploaded here is sent to a server, stored, or shared.
