Excel Data Export Formats

When downloading data from the official data warehouse, you have two export methods:

1) Standard Download (Default)

  • Creates a static Excel file containing a snapshot of the data at the time of download
  • The file will not automatically update when the underlying data changes (e.g., when new school year data is added, when records are updated, or when corrections are made)
  • To access updated data, you must return to this page and download a fresh copy
  • Best for: One-time analysis, archival purposes, or situations where you need a fixed reference point

2) Create Refreshable Workbook (Experimental)

  • Creates an Excel file with a live connection to the official data warehouse
  • The workbook can be refreshed to pull the latest data without re-downloading
  • Updates are retrieved on-demand when you manually refresh the connection in Excel (Data → Refresh All)
  • The connection settings and data source remain embedded in the workbook
  • Note: This is a newer, experimental feature—you may encounter occasional issues
  • Best for: Regular reporting, dashboards, or ongoing analysis where you need current data

Which should I choose?

  • If you need data for a specific point in time or occasional use → use Standard Download
  • If you need to regularly access updated data → use Create Refreshable Workbook

Refresh-able Workbook

Downloading a refreshable workbook creates an Excel file that maintains a live connection to the data warehouse. When the official warehouse data is updated, you can retrieve the latest data in your workbook by choosing Data → Refresh All. This is currently an experimental feature but works reliably in most cases. With a refreshable workbook you can build pivot tables, charts, and other analyses, then update everything instantly by clicking Refresh All.
