What can Harriet do with Word, Excel, and PowerPoint files?

Upload Office formats to the Knowledge Base, use them in automations where supported, and use template-based document generation—not full desktop editing in the assistant.

Harriet supports Microsoft Office–style files in practical ways, but it is not a replacement for the desktop Office apps.

Knowledge Base

You can upload common Office formats (for example Word, PowerPoint) as knowledge documents so Harriet can search and cite them like PDFs or web pages.
Keep files well structured (headings, tables labelled clearly) for better answers.

Document generation (where enabled)

Some skills or workflows generate documents from templates (for example offer letters) and may output Word or PDF depending on configuration.
This is template-driven: you maintain approved templates and variables; Harriet fills them under governance you set.

What Harriet is not doing

Free-form Excel modelling or full slide design as an interactive Office substitute.
Silent editing of arbitrary files on disk without going through supported tools and permissions.

Example

HR uploads a .docx policy to the Knowledge Base; employees ask questions and Harriet quotes the right section. Separately, an onboarding workflow generates a personalised welcome PDF from an approved template.

Guardrails

Sensitive spreadsheets with personal data should use group restrictions like any other knowledge document.
For generated documents, keep legal-approved templates and record which workflow version produced each file.
