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:- Parses the file — Reads rows and columns
- Detects types — Identifies strings, numbers, dates, etc.
- Analyzes patterns — Discovers ID formats, email patterns, etc.
- Finds linkages — Identifies potential relationships between tables
Data Type Detection
AstroBee automatically detects column types:| Detected Type | Examples |

| String | ”John Smith”, “Active”, “SKU-123” |
| Integer | 42, 100, -5 |
| Float | 19.99, 3.14159 |
| Date | 2024-01-15, 01/15/2024 |

Save CSV files with UTF-8 encoding for special characters.
Updating Data
File uploads are one-time imports. To update the data:- Prepare your updated file
- Upload it with the same name
- 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
