Big CSV Viewer

Open a big CSV or TSV in your browser, scroll through hundreds of thousands of rows, search, fix a few cells and export the result.

Open a big table

The file is never uploaded, and only the rows on screen are rendered — that is why a few hundred thousand rows still scroll smoothly.

How it works

  1. 1.Import an Excel, CSV, TSV or JSON file, or paste the table. It is parsed on your own device.
  2. 2.Pick the columns to show: one category axis and up to three values.
  3. 3.Generate once, then keep tweaking — chart type, aggregation, sorting and theme update instantly.
  4. 4.Download an image, or publish the result as an encrypted link that expires on its own.
