Understanding xlsx and odc file formats
XLSX is the default spreadsheet file format used by Microsoft Excel, storing data in a structured, compressed XML-based format. It supports complex calculations, charts, and data manipulation. ODC (Office Data Connection) files, on the other hand, are XML-based files used to store connection information for external data sources, such as databases or web services. ODC files do not contain spreadsheet data but rather the details needed to connect Excel or other Office applications to external data sources.
Can you convert xlsx to odc?
Direct conversion from XLSX to ODC is not typical, as these formats serve different purposes. XLSX contains spreadsheet data, while ODC stores connection settings. However, you can create an ODC file from an Excel workbook if you want to save the connection information for external data sources used within the XLSX file.
How to create an odc file from an xlsx in Excel
If your XLSX file contains data connected to an external source (like SQL Server, Access, or an online database), you can export the connection as an ODC file:
- Open your XLSX file in Microsoft Excel.
- Go to the Data tab.
- In the Connections group, click Connections.
- Select the connection you want to export and click Properties.
- In the Connection Properties dialog, click Export Connection File.
- Choose a location and save the file as an ODC (*.odc).
Best software for xlsx to odc conversion
The most reliable tool for this process is Microsoft Excel (2010 or later). Excel natively supports exporting connection information to ODC files. No third-party converter is needed, as the process is built into Excel's data management features.
Summary
While you cannot convert spreadsheet data directly from XLSX to ODC, you can export external data connection settings from an Excel workbook to an ODC file using Microsoft Excel's built-in features.
