Altair® Panopticon


MS Excel

This is the most commonly used data connector when prototyping, and is used for retrieving data from Excel workbooks or spreadsheets, where for each selected sheet, the first row contains the field/column names, and subsequent rows contain the data.

When in use by the Panopticon Designer (Desktop), the Excel spreadsheet file is queried locally and no copy is made. However when the workbook is published, the spreadsheet will be copied to the Panopticon Visualization Server, effectively creating a snapshot of the data on the server. This is because the server does not necessarily have access or permissions to the source file location.


NOTE: In production use, it is not advised to use a single Excel file as multiple Panopticon data sources. This is because, when using the same Excel file with the data on several sheets, conflicts may occur in reading the file.

A workaround could be to set up a Data Extract with scheduled refresh for each of the datasets in the Excel file, and then let the data tables in your workbook load the data from the Data Extracts.
