DOC to XLSX converter

DOC is a file extension for documents created by Microsoft Word. It is an application in Microsoft Office suite, and one of the most popular word processing programs for Windows and macOS users. Word DOC files may include text, images, objects, styles, and other formatting. Such files are compatible with versions of Word from 1997 onward, and can be opened in many other word processing programs.

When you create a document in Word, it's saved as a DOC file by default. These files contain different kinds of data stored in a binary format, making them much smaller in size than plain text files. If you wish to share a DOC file with someone who doesn't have Microsoft Office installed, you can save it as a PDF (Portable Document Format).

The XLSX file format is a modern extension of the classic XLS file format. It is a Microsoft Excel-sponsored file type designed for storing and exchanging tabular data. An XLSX extension is a collection of multiple binary files stored in an Open Packaging Convention (OPC) container and compressed into one single file.

Due to its compatibility with multiple Office programs and its open XML structure, users can open and edit data stored in an XLSX file easily. Additionally, XLSX files support many features that are not present in the classic XLS file type, such as filters, custom properties, and more robust ways to present data with charts or graphs.
