Frequently asked questions
Are these conversions exact copies of Office documents?
No. Each tool says what it keeps. Data conversions keep cell values; Word conversions keep headings, lists, tables and images; PowerPoint conversions are approximate visual copies. For pixel-exact output, export from Word, Excel or PowerPoint themselves.
Are formulas and macros run?
Never. Spreadsheet tools read saved values only, and macros are not executed.
Which file types are supported?
Modern .xlsx, .docx and .pptx files, plus CSV, TSV and JSON. Older .xls, .doc and .ppt files should be saved in the modern format first.
