DevConverter is an online document converter. Amongst many others, we support PDF, DOCX, PPTX, XLSX. Thanks to our advanced conversion technology the quality of the output will be exactly the same as if the file was saved through the latest Microsoft Office 2019 suite.
The 'M' of DOCM stands for macro. Macros are programs embedded in Office documents used to automate different tasks. Staring from Word 2007, DOCX documents that contain macros are saved with the DOCM extension.
