Everything you need to see your data as a chart

Open data any way you have it

Choose files, drop them anywhere on the page or paste a selection copied from a spreadsheet. Each source opens in its own tab, so you can switch between several files.

• CSV and TSV with automatic delimiter detection
• JSON arrays of objects
• Paste from Excel, Google Sheets or LibreOffice
• Up to 100,000 rows per source

Charts that pick themselves

Every column is recognised as a number, a date or text. From that, Chart Viewer suggests the views that make sense: a line over time, bars by category, a share as a pie. You can always choose the type and the axes yourself.

• Line, bar and pie charts
• Repeated categories are summed
• Empty and non-numeric values are skipped, never drawn as zero
• Your choice is remembered for the same columns

Comfortable to work with

Switch between the chart and a table of the rows behind it, expand the chart to fill the window, and use the interface in English, Russian, German, French or Chinese with light and dark themes.
