Use Codex for Office Files

Choose a checked workflow for spreadsheets, presentations, reports, and PDFs without confusing an editable file with a verified result.

Your job

I need to make or revise a work file with Codex and verify the deliverable.

Where to start

Start with the Office Skills overview, then move to the file type you actually need.

Choose a route

Start with the result you need

Use the condition that matches your work, then check the named output before moving on.

Before you move on: An editable file, a rendered preview, and a source-checked answer are different outcomes. Choose the guide for the file you must hand over, then run its file-specific checks before sharing it.
