This article explains the various methods that you can use to minimize the amount of metadata in your workbooks.
When you create, open, or save a workbook in Microsoft Excel, the workbook may contain content that you do not want to share with others when you distribute the workbook electronically. This information is known as metadata. Metadata is used for a variety of purposes to enhance the editing, viewing, filing, and retrieval of Office documents.
Some metadata is readily accessible through the Excel user interface. Other metadata is only accessible through extraordinary means, such as by opening a workbook in a low-level binary file editor.
The following are some examples of metadata that may be stored in your workbooks:
Metadata is created in a variety of ways in Excel workbooks. As a result, there is no single method to remove all such content from your workbooks. The following sections describe areas where metadata may be saved in Excel workbooks.

In Microsoft Excel, comments appear as a small red triangle in the upper-right corner of a cell. To view comments, right-click the cell, and then click Delete Comment on the shortcut menu.

In Microsoft Excel, save your workbook in an older file format, such as SYLK, Excel 4.0, or Lotus 1-2-3 format. Close the workbook, and then reopen the new file. Because the routing slip information is no longer present, you can now save your file as a Microsoft Excel workbook.
You can also follow these steps:

To delete this information from the workbook, follow these steps:
Note Because of the space limitation of a floppy disk (usually 1.44 MB), this method cannot be used if the workbook file size exceeds the amount of free space on the floppy disk.
Embedded Objects in Workbooks May Contain MetadataIf you embed an object in a workbook, the object still retains its own properties, regardless of what you do to the workbook. For example, if you embed a Microsoft Word document in a Microsoft Excel workbook, the document and the workbook each have their own properties.
You can delete metadata from an embedded object by opening the object, removing any metadata, reactivating the container document (in the previous example, this is the Excel workbook), and then saving the container document.
Note When you open an embedded object in a workbook, only part of the embedded object is displayed in the workbook. The object may contain additional information that does not appear. If you want a workbook to contain only a rendering of the embedded object, and not the actual contents, follow these steps:
