What this tool does

Open CSV as a table in your browser. Inspect headers, search and filter rows, and check delimiters in a paginated preview before importing your data.

How to use

Paste a CSV table with a header row to inspect its columns and rows.

Features

Inspect a bounded table preview, choose delimiters and review parsed row and column counts.

When to use it

Check the structure of an exported dataset before importing it into another application.

Example and checks

This small fixture has a quoted comma inside one cell. Choose the correct delimiter before judging column counts. The table preview is paginated, but parsing and filtering still use browser memory; a bounded preview is not a promise of unlimited file size.

Common questions

Does the preview show every row of a large CSV?

Preview pages contain 50 rows and up to 100 columns. Search, sorting and filters cover the full table.
