Convert DWT to XLSM via Java

What is DWT file format?

DWT, or Design Web Format, is a proprietary file format created and maintained by Autodesk, Inc., a leader in computer-aided design software. DWT files are used to store the design of a web page layout, detailing the structure, design elements, and content. These files are used as part of the Autodesk web design process, which allows web designers to quickly create consistent designs across multiple web pages. DWT files store a range of information, including the physical layout of the web page, the text and graphics used, and any formatting or other design elements incorporated into the page. DWT files are not standard web documents, but instead contain information about how the web page should be designed. For example, a DWT file could include detailed information about the setup and navigation of a page, including links to other pages, page titles, and background images. Additionally, DWT files also provide web design elements such as font type, page width, page margins, and page layout. DWT files are typically used in commercial web design packages, such as Adobe Dreamweaver. These packages use DWT files as templates for creating web designs, which can then be modified to create unique pages. In addition, DWT files can also be used to transfer existing Adobe Illustrator designs into HTML and other web-friendly formats. Overall, Autodesk’s DWT file format is an important part of the modern web design process. It is a powerful tool that allows designers to quickly create and manage consistent web designs with ease. It is also a great way to transfer existing Adobe Illustrator designs into web-friendly formats.

What is XLSM file format?

The XLSM file format is an extension of the XLSX file format used for Microsoft Excel workbooks. Similar to XLSX, it is based on the Open XML file format and is associated with the Excel application. The “M” in XLSM stands for “macro-enabled”, indicating that it supports the inclusion of macros.

XLSM files store spreadsheet data, including worksheets, formulas, charts, and other elements commonly found in Excel workbooks. Additionally, XLSM files allow the embedding of VBA (Visual Basic for Applications) macros within the workbook. Macros are scripts written in VBA that automate tasks, perform calculations, and interact with the spreadsheet data.

By including macros in XLSM files, users can create customized functions, automate repetitive tasks, and enhance the functionality of their Excel workbooks. Macros can be written to manipulate data, generate reports, perform complex calculations, or interact with other applications.

When opening an XLSM file, Excel prompts the user to enable or disable macros due to security concerns. Enabling macros allows the embedded VBA code to execute, while disabling macros prevents potential security risks associated with malicious code.

XLSM files provide advanced features and customization options for Excel users who require automation beyond the capabilities of the standard XLSX format. They are commonly used in business environments, financial modeling, data analysis, and other scenarios where complex calculations and automation are necessary.
