Codex Annotations Expands to Documents, Spreadsheets & Slides
CodexOpenAI expanded Codex Annotations on June 2, 2026 to support in-place editing of documents, spreadsheets, and slides, building on the existing capability that already worked for code, Markdown files, and websites. Users highlight a specific element and tell Codex exactly what to change, whether that is a chart label on a slide, a claim in an investment thesis, or a font in a navigation bar. This precision editing model avoids full regeneration and lets teams iterate on the exact pieces they want without disturbing content they have already approved.

Targeted Editing Without Starting Over
A persistent frustration with AI-generated content is the all-or-nothing regeneration problem: if a user wants to tweak one section of a document, they often have to re-prompt from scratch or accept unwanted changes elsewhere. Codex Annotations directly addresses this.
OpenAI introduced Annotations for code, Markdown, and websites earlier in Codex's lifecycle. The June 2, 2026 expansion brings the same targeted editing model to documents, spreadsheets, and slides: the core formats used by knowledge workers in day-to-day business operations.
How Annotations Work
The interaction model is direct: highlight the exact element you want to change, then tell Codex what to do with it. The system maps the underlying data schema of the document, so when a user selects a block of cells in a financial model, Codex isolates those exact data arrays and scopes its operation accordingly.
Practical examples of the expanded Annotations capability include:
- Select the navigation bar in a hosted Sites app and ask Codex to update the font.
- Highlight a factual claim in an investment thesis and ask Codex where it came from.
- Mark a chart on a slide and ask for a clearer axis label.
- Select a row range in a spreadsheet and ask Codex to reformulate the underlying logic.
In each case, Codex focuses the update on the selected element and leaves everything else intact.
Connection to the June 2 Launch
Annotations is one of three major capabilities OpenAI announced on June 2, alongside Codex Sites (hosted web app deployment) and six role-specific plugins for knowledge workers. Together, these features signal OpenAI's intent to position Codex as a document and application work platform, not just a code generation tool. For teams already using Codex for coding workflows, Annotations provides a natural bridge into document-centric work.
