With Codex, finance teams can just build things. Start with the close workbooks, revenue and expense dashboards, forecast updates, prior MBRs, and owner notes you already use. Codex can help turn that context into tangible assets your team can review, refine, and share, no coding required. Use it to spend less time assembling the first pass and more time shaping the story, checking the numbers, and preparing for the decisions ahead.

Learn more about using Codex for everyday work in our on-demand webinar⁠.

Top 10 Codex use cases for finance teams

Ready to try Codex with real finance work? Start with a copy-ready prompt, then use the fully built example to see how that same prompt gets stronger with real files, systems, constraints, and review expectations. Each use case also includes suggested skills and plugins to help Codex work across your tech stack, so your team can get to a reviewable first pass faster and spend more time on the judgment, analysis, and decisions that matter.

1. Monthly business review narrative

Why people use this

Turn close outputs, forecast updates, and owner commentary into a CFO-ready monthly business review narrative.

How it works

1. Review close workbooks, dashboards, forecast updates, prior MBRs, and owner notes. 2. Identify key variances, what changed since forecast, risks, and CFO prep questions. 3. Draft the narrative with source-backed numbers and owner follow-ups.

Prompt to try

Try it out

Prepare the [month/quarter] management business review story for [business/team]. Use the close workbook, revenue and expense dashboards, forecast update, prior MBR, owner notes, and finance close context I provide. Draft an executive-ready narrative with key variances, what changed since forecast, risks, CFO prep questions, and follow-ups by owner. Cite a workbook tab, dashboard, or source note for every material number.

How to customize it

Swap in the real month or quarter, business team, close workbook, dashboards, forecast update, prior MBR, and owner notes. Tell Codex what audience the narrative is for, which metrics matter most, and how every number should be cited. Ask it to flag missing support, stale prior-month language, risks, and CFO prep questions.

Suggested plugins: Google Drive, SharePoint, Box, Spreadsheets, Presentations, Documents, Slack, Teams, Gmail, Outlook Email.

Example:

Prepare Acme’s April management business review story for the Enterprise Sales team. Use “April Close Workbook.xlsx,” “April Revenue Dashboard,” “April Forecast Update,” “March MBR Deck.pptx,” owner notes in “April MBR Owner Inputs,” #finance-close from April 22 through April 30, and any related close context I provide.

Draft an executive-ready narrative with key revenue and expense variances, what changed since forecast, risks, CFO prep questions, and follow-ups by owner. Cite a workbook tab, dashboard, or source note for every material number. Create the draft as a Microsoft Word document named “Monthly Business Review Narrative.”

2. Finance model cleanup and analysis

Why people use this

Improve model reliability before high-stakes reviews by catching formula, structure, source, and assumption issues.

How it works

1. Review workbook structure, formulas, hardcodes, links, checks, and output tabs. 2. Make safe cleanup changes and flag assumptions that require finance-owner review. 3. Return a cleaned model where appropriate plus a severity-ranked QA memo.

Prompt to try

Try it out

Clean and review [model name] before it goes to [audience]. Check workbook structure, formulas, hardcodes, broken links, circulars, sign conventions, period labels, source tie-outs, checks, and output tabs. Make safe cleanup changes where appropriate, but do not change business assumptions without calling them out. Return a cleaned model if safe, plus a QA memo with high-risk issues, fixes made, remaining assumptions, and cells or tabs that need finance-owner review.

How to customize it

Swap in the actual model name, audience, and supporting source files. Tell Codex which tabs matter most, what kinds of cleanup are safe, and which business assumptions should not be changed without review. Ask for both a cleaned workbook and a severity-ranked QA memo.

Suggested plugins: Spreadsheets, Google Drive, SharePoint, Box, Documents, Slack, Teams, Gmail, Outlook Email.

Example:

Clean and review “FY27 Operating Plan Model.xlsx” before it goes to the leadership team. Check workbook structure, formulas, hardcodes, broken links, circular references, sign conventions, period labels, source tie-outs, model checks, and output tabs.

Make safe cleanup changes where appropriate, but do not change business assumptions without calling them out. Return a cleaned workbook if safe, plus a QA memo with high-risk issues, fixes made, remaining assumptions, and cells or tabs that need finance-owner review. Pay special attention to the “Revenue Drivers,” “Headcount Plan,” “Cash Forecast,” and “Exec Summary” tabs.

3. Recurring CFO and board reporting pack

Why people use this

Speed recurring executive reporting by refreshing metrics, commentary, and open questions from the latest source materials.

How it works

1. Review the latest forecast model, KPI dashboard, prior pack, cash view, and owner inputs. 2. Update metrics, deltas, charts, and commentary. 3. Summarize what changed, what remains open, and which sections need executive review.

Prompt to try

Try it out

Refresh the [CFO/board] reporting pack for [month/quarter]. Use the latest forecast model, KPI dashboard, prior pack, cash view, forecast notes, owner inputs, and open questions I provide. Update key metrics, deltas, charts, and commentary. Create a pack summary that explains what changed, what needs owner input, which assumptions remain open, and which slides or sections need executive review.

How to customize it

Swap in the reporting period, latest forecast model, KPI dashboard, prior pack, cash view, forecast notes, and owner inputs. Tell Codex which slides or sections should be refreshed, what should stay unchanged, and how open assumptions or missing owner inputs should be flagged.
