About the CSV Viewer

Inspect delimited data in a scrollable table before opening it in a full spreadsheet application.

How to use it

  1. Paste CSV or select a local file.
  2. Choose the matching delimiter.
  3. View the row and column summary with a limited table preview.

Preview behavior

The browser parses every row for the summary but renders at most the first 100 rows to keep the page responsive.

Example

A contact export can be checked for its header and first records before further processing.

MVP limits

The viewer treats every cell as plain text. It does not execute formulas, macros or scripts and does not edit the source file.
