# HTML Export Reference Implementation

The KeyView Export SDK includes a reference implementation that demonstrates how to export documents to HTML. The reference implementation includes source code for a library named `libkvhtmlexport`, and a sample program named `kvhtmlexport`.

The `libkvhtmlexport` library is written in C++ and provides a simple interface to HTML Export. You can:

- use the library in your own product, if it provides the functionality you need.
- modify the library to provide the functionality you desire.
- look at the source code to help you learn how to use the C API, which provides much greater flexibility.

The library uses partition information provided by KeyView to provide the following features out-of-the-box:

- A "print" view for word-processor documents. This creates a web page containing a representation of the original document, which is easy to read because it uses the correct page widths and margins.
- A "tabbed" view for spreadsheet files. This shows spreadsheets using a familiar tabbed interface, with one worksheet on each tab.
- A "list" view for presentations. This displays multiple slides, arranged in a vertical column one after another, on a single web page.
- A "full screen" view for presentations. This displays one slide at a time. You can navigate between slides using the arrow keys on your keyboard or the scroll wheel on your mouse.

The following image shows a Microsoft Word document that has been exported to HTML, being displayed in a web browser:

The following image shows a Microsoft Excel workbook that has been exported to HTML, being displayed in a web browser. Additional sheets can be viewed by clicking the tabs at the bottom of the window.

The interface for the library is in `htmlexport/libkvhtmlexport/include/libkvhtmlexport.h`, and the implementation is in `htmlexport/libkvhtmlexport/src/`.

The `kvhtmlexport` sample program uses the library to convert documents to HTML. The source code is provided in `htmlexport/libkvhtmlexport/sample/src/`. A compiled binary is also provided, in the `PLATFORM/bin` folder, so that you can try it without having to build it yourself. For more information, see kvhtmlexport.

NOTE: The compiled binary for `kvhtmlexport` has an embedded trial license, which expires approximately five months after release.
