Convert DOC to XLSM in C# .NET

What is DOC file format?

The DOC file format, initially developed by Microsoft in the early 1990s for their renowned word processing software, Microsoft Word, continues to be widely utilized today and remains closely associated with the Microsoft Office suite. DOC files store documents in ASCII text format, preserving special formatting such as bold, italics, and underlined text. Moreover, they retain essential elements like images, diagrams, charts, tables, and other formatting elements used within the document.

A prominent advantage of the DOC format lies in its compatibility with a diverse range of software applications, including WordPerfect, OpenOffice, and various office suites. This compatibility facilitates seamless sharing and collaboration on documents across different platforms. Additionally, DOC files can be effortlessly accessed and opened using most web browsers, enabling convenient online document viewing and sharing.

The simplicity and user-friendliness of the DOC format contribute significantly to its widespread popularity. Microsoft Word offers an intuitive environment for creating, editing, and formatting documents, making it an accessible choice for users. The format’s extensive adoption and support further ensure that DOC files can be accessed and opened by a vast majority of users, fostering effective collaboration and communication.

Furthermore, the DOC format boasts reliability and security features. DOC files are designed to be resistant to data corruption, preserving the integrity of documents over time. This reliability ensures that crucial information remains intact and accessible. Additionally, the format supports various encryption options, empowering users to safeguard sensitive information within their documents, enhancing privacy and data security.

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.
