Excel Services API
The benefits of Excel Services extend beyond the end user. With the Excel Services
application programming interface (API), corporate developers can take advantage of the
powerful calculation engine in Excel in other applications. By using the Excel Services
API, developers can control and perform other functions, such as:
Loading an Office Excel 2007 spreadsheet on the server.
Changing the values in one or more cells of a spreadsheet—either by changing a
cell's value or by refreshing an external data connection—and recalculating the
spreadsheet based on these new values.
Retrieving all or part of a spreadsheet for viewing or to use within a larger
business process.
Support for New File Formats
Office Excel 2007 offers support for new file formats that improve data integration, boost
performance, and make it easier to share business information across platforms.
Office XML Formats
Office Excel 2007 supports the new Ecma Office XML Formats. The Excel XML Formats
improve data integration between Microsoft Office system documents and back-end
systems. The file formats have open, published format specifications that any technology
provider can use to integrate Microsoft Office system documents into their solutions.
Because the file formats are compressed, they result in substantially smaller file sizes
than with previous versions of Excel, Word, and PowerPoint, thereby reducing storage
and bandwidth requirements. Segmented data storage within the file formats greatly aids
in recovering corrupt documents because the corruption of any part of a document does
not prevent you from opening the entire document.
Support for XPS and PDF
When you need to create a fixed version of your spreadsheet, you can now save it as an
XML Paper Specification (XPS) file or Portable Document Format (PDF) file. This “locks”
your data while providing a polished report for customers.
