Processing rules and limitations

  • Input limits

    Files are limited to 25 MiB, 100,000 rows, and 100 columns.

  • Scatter data

    Each plotted row needs numeric values for both the X and Y axes.

  • Aggregation

    When aggregation is enabled, rows with the same category are combined using the selected calculation.

Spreadsheet data stays in the browser

The selected file, cell data, chart rendering, and export are handled locally and are not uploaded to this site's server.

Frequently asked questions

Why are CSV characters garbled?

Save the CSV as UTF-8 and open it again. The tool does not guess every legacy CSV encoding.

Are spreadsheet formulas recalculated?

No. The tool reads values stored in the file and does not run the spreadsheet calculation engine.

Why does a pie chart show fewer values?

Pie charts group values by category and are clearest with a small number of positive categories.
