An experienced statistical programmer details their use of n8n and OnlyOffice to generate custom timesheet reports using a combination of Markdown, JavaScript, and HTML. The workflow involves using n8n's nodes to process raw data, sort and merge information, and ultimately create a Markdown document, which is then converted into an HTML report. This process circumvents the limitations of OnlyOffice's integration features by utilizing the OnlyOffice API and n8n's automation capabilities. The programmer provides a tutorial on setting up this workflow, emphasizing the flexibility of n8n and the importance of understanding JavaScript and Markdown to customize outputs effectively. The tutorial also highlights the benefits of embedding images as base64 strings to ensure compatibility and ease of report distribution.
