How it works
Drop the file onto the page or choose it with Open file. The first row becomes the column names, the delimiter (comma, semicolon, tab or pipe) is detected, and each column is recognised as a number, a date or text.
- Quoted values and commas inside quotes are handled
- Byte-order marks and blank lines are ignored
- Repeated header rows and log footers are skipped and reported
The right chart for your columns
A date column with a number gives a line over time. A text column with a number gives bars or a pie. If nothing fits, the values are drawn against the row number. You can change the chart type and both axes at any time.
Large files
Files with up to 100,000 rows are charted in full. When a file has more, the first 100,000 rows are used and the page says so, so the picture is never silently cut.
