About this file format

.csv (Comma-Separated Values) is a plain-text format for tabular data, defined by RFC 4180. Each line is a row and each field is separated by a delimiter (usually a comma). Because it is simple and universal, CSV is the standard interchange format for moving tabular data between databases, spreadsheets, and applications.

CSV Viewer

Description

Free online CSV viewer. Open .csv files directly in your browser without uploading them.

Overview

This CSV viewer renders comma-separated values files locally in your browser. CSV is the most common plain-text format for tabular data, used for exports, imports, and data exchange between applications. Pick a sample or choose your own .csv file to inspect rows and columns without a spreadsheet app.

When to use

  • You received a .csv export and only need to read or scan it.
  • You want a quick private preview before importing data into another tool.
  • You are on a device without Excel or Google Sheets and need to view a table.

How it works

  1. 1Select a built-in sample or choose your own .csv file.
  2. 2The viewer parses the delimited text and renders it as a table in the browser with no upload.
  3. 3Read the data, then switch samples or load another file any time.

Use cases

  • Reviewing data exports from databases, CRMs, or analytics tools.
  • Previewing a delimited file before importing it into a spreadsheet.
  • Quickly scanning a large or unfamiliar CSV without opening a heavy app.

FAQ

Is this CSV viewer free?

Yes. It runs in your browser for free and needs no registration or installation.

Are my .csv files uploaded?

No. Files opened from your device stay on your device. Only public sample files come from the server.

Does it support other delimiters?

CSV commonly uses commas, but the viewer also handles common delimited text. For very unusual encodings or delimiters, a dedicated spreadsheet app may give better results.
