CSV Viewer

This lesson is part of Web Developer Tools · All levels

Summary

The CSV viewer reads the comma-separated values file and displays it as an easy-to-check table. You can see columns, the number of rows, and the values that might contain extra quotes or separators. Viewer helps detect delimiter and encoding problems before data is processed further.

Key points

CSV stores tabular data as text with a specific separator
The values containing the comma must be quoted
The first line is often used as a column name
The delimiter can be a comma, a semicolon, or a tab
CSV doesn't store the data type so the numbers need to be converted
