Connecting a CSV Source

To bring data in from a CSV file:

  1. Create a new source -- Click the add button and select CSV as your source type
  2. Upload your file -- Select a .csv file from your computer (up to 250 MB)
  3. Wait for processing -- Galdera reads your file and detects the columns. This usually takes 2-5 minutes.
  4. Map your columns -- Once processing completes, you'll see a column mapping screen:
    • Target columns: Select which numeric columns contain the values you want to forecast (e.g., revenue, costs, headcount). Each becomes a measure.
    • Dimension columns: Select which categorical columns you want to slice data by (e.g., region, product, department). Each becomes a dimension.
    • Date column: Tell Galdera which column contains your dates (e.g., "month" or "date")
  5. Save -- Galdera creates your measures and dimensions. You're ready to forecast.
Tips:
  • Column names become measure and dimension names -- use clear, descriptive headers in your CSV
  • Galdera auto-detects whether your data is in wide format (multiple numeric columns) or long format (one name column + one value column)
  • If an upload fails, you can retry or restore to your last successful configuration
