Clipboard Format Spy

Displays various formats currently on the clipboard

Version 4.1.1
Released 21 Mar 2104
O/S Windows 2000 & later


Clipboard Format Spy lists the available formats for any data that is currently stored on the clipboard. It automatically updates the information displayed as the contents of the clipboard change. For certain formats you can also view the clipboard contents. The clipboard can also be cleared.

For each format displayed on the clipboard, the following information is displayed in the main window.

  • Code – this is the identifier used to represent the clipboard format. It is displayed in hexadecimal.
  • Description – this is the description of the clipboard format. Symbolic constants are displayed for the Windows standard clipboard formats.
  • Size – this is the size of the data on the clipboard. No value is displayed if the clipboard contents are not stored in global memory.

The display can be sorted in ascending or descending order on any column.

Clipboard formats can be viewed by selecting the required format in the main display and right-clicking to display a pop-up menu. Select the required viewer from the menu. If the format can't be viewed then "no viewer" will be displayed in the menu.

The file name of the process that owns the clipboard is displayed in the status bar.
