For text-based files, there’s an additional 8 million character limit and a 5,000 page PDF processing limit. A file can upload before processing reports a page or character limit failure. Knowledge bases accept supported text based formats such as PDF, DOCX, TXT, Markdown, and presentations.
Tabular Files:
Tabular files can be uploaded directly in chat, Agents, and Library Folders for active file work. Folder Sync supports spreadsheets from SharePoint, Google Drive, and OneDrive. Confluence Cloud Folder Sync imports pages from named folders, not page attachments. Tabular files cannot be uploaded to Knowledge bases. Spreadsheets in Recent Files support preview with sheet tabs, zoom, column resizing, and formula inspection, except for Parquet and the
.xlam Excel add-in format. For technical details, see tabular files in Knowledge bases.
Images:
Images can be uploaded in chat conversations, Agent chats, and Library Folders. Langdock converts SVG files to JPEG during upload. Images cannot be uploaded to Knowledge bases or Agent knowledge.

FAQ
Why is my supported file not working?
Why is my supported file not working?
A file type can be generally supported but still fail because of file size, corruption, password protection, scan quality, unusual encoding, or content that cannot be extracted reliably. Try a smaller or cleaner version of the file and check whether the file works as a direct upload or should be converted first.
Are spreadsheets handled the same way as text documents?
Are spreadsheets handled the same way as text documents?
No. Spreadsheets and tabular files often need different handling from text documents. If exact rows, formulas, or calculations matter, use the file directly in a chat or workflow designed for data analysis instead of assuming it will behave like a text document in retrieval.
