Merge Tables

Combine several Excel or CSV files into one table — columns line up by header name, and you can add a column that records which file each row came from. Everything runs in your browser.

Your data never leaves this browser

The file is parsed, previewed and charted on your own device. Nothing is uploaded — not even a sample. Close the tab and the data is gone.

How it works

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