$ data-build.py buildfile.json

buildfile.json contains a list of operations to be performed on data. Think of it as a script for a spreadsheet.

An example of build file could be:

[
  {
    "function": "sheets.import_data",
    "description": "Importing data from csv file",
    "params": {
      "sheet": "dataset1",
      "format": "csv",
      "filename": "dataset1.csv",
      "skip_last_lines": 1
    }
  },
  {
    "function": "columns.add_column",
    "description": "Calculate the gender ratio",
    "params": {
      "sheet": "dataset1",
      "name": "Gender Ratio",
      "expression": {
        "language": "python",
        "content": "return float(row['Male Total']) / float(row['Female Total'])"
      }
    }
  },
  {
    "function": "sheets.export_data",
    "description": "",
    "params": {
      "sheet": "dataset1",
      "format": "csv",
      "filename": "dataset2.csv"
    }
  }
]

YAML buildfiles are also supported. databuild will guess the type based on the extension.
