We expanded file input types so you can now pass docx, pptx, csv, xlsx, and more directly to the Responses API. Your agents can now pull context from real-world files and generate more accurate outputs. https://t.co/brKUsSfOJy https://t.co/no5zPgWgSv
OpenAI Responses API Now Accepts Word, Excel, and PowerPoint Files
· Updated
OpenAI expanded file input support in the Responses API to include
.docx, .pptx, .xlsx, .csv, .tsv, .txt, and code files - formats agents encounter constantly in real-world enterprise workflows. PDF support already existed; this closes the gap for the office document formats that make up the bulk of business data.The API handles each type differently: text is extracted from Word and PowerPoint files, while spreadsheets get a special augmentation flow optimized for structured data. One limitation: embedded charts and images in non-PDF files aren't extracted - convert to PDF first if you need visual fidelity.
This significantly reduces pre-processing overhead for document-heavy agents. Pass a .docx meeting summary or an .xlsx financial report directly in your API call and let the model pull context without an intermediate extraction step.
