Convert POTM to DIF in Java

What is POTM file format?

A POTM file refers to a macro-enabled presentation template created using Microsoft PowerPoint, a software program used for creating slide show presentations. It includes default images, slide templates, macros, and formatting. POTM files are commonly used by PowerPoint users to create multiple .PPTM files with consistent designs and macro settings.

POTM files offer additional functionality compared to typical presentation files, as they support macros. Macros are script-like functions that automate repetitive tasks within PowerPoint. Users can record macros that can be replayed to perform specific actions and assign them to buttons or keystrokes for convenient execution. To record a macro, users can select View → Macros in PowerPoint.

For general presentation creation, users can save their files as .PPTX or .POTX files. However, if they want to create a template that incorporates macros, they can save their presentation as a POTM file.

It’s worth noting that POTM files were introduced by Microsoft when they released Microsoft Office 2007.

To open a POTM file, Microsoft PowerPoint (2007 or later) is the recommended application for full support of presentation formatting and embedded macros on both Windows and macOS. Alternative applications like Apache OpenOffice Impress, Kingsoft Presentation, and Apple Keynote can also open POTM files, but some formatting and macros may not be fully preserved. For Mac users looking to view a POTM file without editing, Apple Preview (bundled with macOS) or Google Drive, a free cloud storage service, can be used.

Online platforms like Google Slides allow users to upload POTM files for viewing, editing, and conversion. However, it’s important to note that Google Slides does not support macros.

To convert a POTM file, various presentation applications including Microsoft PowerPoint, Apple Keynote, and OpenOffice Impress offer conversion capabilities. In Microsoft PowerPoint for Windows and Mac, users can select File → Save As and choose from formats such as .PPTX, .PPT, .PDF, .ODP, .XPS, .MP4, .WMV, .JPEG, and .PNG to convert the POTM file to their desired format.

What is DIF file format?

DIF (Data Interchange Format) is an ASCII-based, tabular format for exchanging data between different programs and platforms. It is a text-based data exchange format developed by Lotus, a spreadsheet program. It stores data in a tabular form and supports basic data types, such as numbers and strings. DIF was initially developed to store spreadsheet data, but it is also used to transfer data between relational databases, non-relational databases, spreadsheets, text editors and other programs. It supports multiple sheets, columns, titles and comments. It also has features to help protect the integrity of the data, such as automatic type checking and range checking. DIF is still popular today, and is supported by several popular tools, such as Microsoft Excel, LibreOffice Calc, and GNUstep. It is also used by some development frameworks and programming languages, such as Delphi and Visual Basic. In short, DIF is a reliable and easy-to-use data exchange format that is still used in many programs and platforms today. It is a great choice for exchanging data between different programs and platforms, and is also a good option for archiving data.
