I’m building a Windows-only desktop dashboard that lets my team keep everything in one place. The app has to accept and display a wide mix of files—PDF, JPEG/PNG images, DOCX, XLSX, CSV and anything else Windows can preview—through a simple drag-and-drop or “Add File” action. Once attached, each item should open inside the same window, ideally via an embedded viewer so users never leave the dashboard. A second core area is live data visualisation. From any loaded table or imported spreadsheet the user chooses the columns, clicks “Generate”, and the app should instantly render bar, pie or line charts that can be resized, filtered and exported. Data tables themselves need to support filtering, sorting and inline edits. On top of that I want a dedicated “Excel Merger” tab: the user picks a master sheet, adds one or more secondary sheets, and if their column names match the tool merges them automatically, shows a preview, then saves to a new workbook. Quick-link tiles (URLs, network paths, SharePoint items, etc.) sit along the side so teammates can open common resources without hunting through bookmarks. Every page—files, charts, tables, links—stays inside the same dashboard frame for a cohesive feel. Key deliverables • Windows installer (.exe) plus full source ,should not be .exe • Embedded viewers for PDF, images and Office docs • Dynamic bar, pie and line charts from selectable datasets • Excel/CSV import with column-matching merge tool • Searchable, editable data-grid component • Quick-link panel with one-click launch • User-level data store (SQLite or equivalent) so each person runs the app independently • README covering build, install and dependency setup If you prefer WPF/.NET, Electron, or another Windows-friendly stack, I’m open—just keep the interface clean and the workflow snappy. Let me know what libraries you plan to use for file preview and charting, and we can get started right away.
