  "textContent": "In addition to the new file types, there’s specific file types augmentation for data (xlsx, csv, etc):\n\n> Instead of passing entire sheets to the model, the API parses up to the first 1,000 rows per sheet and adds model-generated summary and header metadata so the model can work from a smaller, structured view of the data.\n\nCategory | Common extensions\n---|---\nPDF files | .pdf\nText and code | .txt, .md, .json, .html, .xml, code files\nRich documents | .doc, .docx, .rtf, .odt\nPresentations | .ppt, .pptx\nSpreadsheets | .csv, .xls, .xlsx\n\nRead more:\n\ndevelopers.openai.com\n\n### File inputs | OpenAI API\n\nLearn how to use files as file inputs in the OpenAI API.\n\nx.com\n\n#### OpenAI Developers\n\n@OpenAIDevs\n\nWe 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. developers.openai.com/api/docs/guide… pic.x.com/no5zPgWgSv\n\n10:15 PM - 24 Feb 2026 78  5",
