Multiple Files

Upload multiple files at once to create a data source with multiple tables. Each file becomes a separate table.

Excel Workbooks

For Excel files with multiple sheets, each sheet becomes a separate table within the data source.

After Upload

Once uploaded, AstroBee:
  1. Parses the file — Reads rows and columns
  2. Detects types — Identifies strings, numbers, dates, etc.
  3. Analyzes patterns — Discovers ID formats, email patterns, etc.
  4. Finds linkages — Identifies potential relationships between tables

Data Type Detection

AstroBee automatically detects column types:
Detected TypeExamples
String”John Smith”, “Active”, “SKU-123”
Integer42, 100, -5
Float19.99, 3.14159
Date2024-01-15, 01/15/2024
Datetime2024-01-15 14:30:00
Booleantrue, false, yes, no
If types are detected incorrectly, ensure your source data is consistently formatted. For example, don’t mix “N/A” text in a numeric column.

Best Practices

Include column headers in the first row. AstroBee uses these as field names.
Keep data types consistent within columns. Don’t mix numbers and text.
Use descriptive column names like “customer_id” instead of “id1”.
Remove empty rows and columns before uploading.
Save CSV files with UTF-8 encoding for special characters.

Updating Data

File uploads are one-time imports. To update the data:
  1. Prepare your updated file
  2. Upload it with the same name
  3. The existing data is replaced
For data that changes frequently, consider using an external connector with automatic sync instead.

Limitations

  • Maximum file size: 300 MB
  • Maximum rows: No hard limit, but very large files may take longer to process
  • Password-protected Excel files are not supported
