Read and write real documents on the device - PDF, XLSX, DOCX, PPTX and CSV. Turn a photo or picture into a PDF, generate a PDF report or a slide deck from structured input, build a spreadsheet whose formulas carry computed values, extract text and tables out of a PDF or an Office file, and compute sums, means and groupings over a CSV or XLSX. Use whenever the user asks to convert an image to a PDF, to analyse a document or a table, or to produce a report, deck, spreadsheet or Word document.
