Expected Data Formats

CSV Format

CSV files should have a header row followed by data rows. You can also include metadata in comment lines (starting with #).

Example CSV:

# title: Quarterly Sales Comparison
# type: bar
# colors: #80208f,#ba68c8
Quarter,2023,2024
Q1,5000,6000
Q2,7000,8000
Q3,8000,9000
Q4,6000,1500

How the Header Row Works:

The first column in the header row is for your labels (such as categories, time periods, or names). Each additional column is a dataset or series (such as years, products, or groups you want to compare). For example, in Quarter,2023,2024:

  • Quarter is the label for each row (e.g., Q1, Q2, Q3, Q4).
  • 2023 and 2024 are datasets/series. These will appear as separate series in bar/line charts, or as selectable datasets in pie/doughnut charts.
Header Purpose
Quarter Label for each row (category or time period)
2023 Dataset/series (e.g., values for 2023)
2024 Dataset/series (e.g., values for 2024)

How Data Rows Work:

  • The first value in each row is the label (e.g., Q1).
  • The remaining values are the data for each dataset/series (e.g., 5000 for 2023, 6000 for 2024).

Supported Metadata:

  • # title: Your Chart Title - Sets the chart title
  • # type: bar|line|pie|doughnut - Sets the chart type
  • # colors: #hex1,#hex2,... - Sets custom colors for data series

How Colors Work:

For bar and line charts, colors are applied to each data series (column) in order:

# colors: #80208f,#ba68c8,#9c27b0
Month,Sales,Expenses,Profit
January,1000,600,400
February,1200,650,550

In this example:

  • Sales data will be purple (#80208f)
  • Expenses data will be light purple (#ba68c8)
  • Profit data will be deep purple (#9c27b0)

For pie and doughnut charts, colors are applied to each slice in order:

# type: pie
# colors: #80208f,#ba68c8,#9c27b0
Category,Value
Category A,100
Category B,200
Category C,300

In this example:

  • Category A will be purple (#80208f)
  • Category B will be light purple (#ba68c8)
  • Category C will be deep purple (#9c27b0)

If you don't specify colors, the tool will automatically assign colors from its default palette.
