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(opens in a new window).

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.

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

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.

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.”

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

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.

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.

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

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.

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.

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

Example:

Refresh Acme’s May CFO reporting pack. Use “May Forecast Model.xlsx,” “May KPI Dashboard,” “April Board Pack.pptx,” “May Cash View,” “Forecast Notes - May,” owner inputs in “CFO Pack Open Questions,” and related discussion from #cfo-staff.

Update the key metrics, deltas, charts, and commentary. Create a CFO-ready pack summary that explains what changed since the April board pack, what still needs owner input, which assumptions remain open, and which slides or sections need executive review. Do not invent metrics. Flag any number that cannot be tied back to the forecast model, KPI dashboard, cash view, or owner notes.

Turn budget, forecast, and actuals movement into a clear variance bridge leaders can trust and act on.

1. Review close workbooks, budgets, forecasts, dashboards, trackers, and owner notes.
2. Build a driver bridge across revenue, margin, opex, cash flow, and balance-sheet items where relevant.
3. Flag unsupported variances and draft owner-ready follow-up questions.

Swap in the comparison period, actuals, budget, prior forecast, dashboards, trackers, and finance owner notes. Tell Codex which P&L, cash flow, or balance-sheet lines to bridge and how to handle unsupported variances. Ask it to separate confirmed drivers from questions for owners.

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

Example:

Explain Acme’s April forecast-to-actual movement. Use “April Close Workbook.xlsx,” “FY26 Budget.xlsx,” “March Forecast.xlsx,” “April Revenue Dashboard,” “April Opex Tracker,” “April Cash View,” and finance owner notes from #finance-close.

Build a variance bridge across revenue, gross margin, opex, EBITDA, free cash flow, and balance-sheet drivers where relevant. Draft owner-ready follow-up questions, reconcile source breaks, and flag any variance that is not supported by a source. Cite the workbook tab, dashboard, tracker, or owner note behind each material driver.

Help finance teams update forecasts and compare scenarios quickly as assumptions, actuals, and leadership priorities change.

1. Review the operating model, driver model, headcount plan, cash forecast, actuals, and assumptions.
2. Build base, downside, and upside scenarios with key sensitivities.
3. Summarize cash impact, hiring implications, trigger points, and approval needs.

Swap in the forecast or operating plan, driver model, headcount plan, cash forecast, latest actuals, approved assumptions, and leadership notes. Tell Codex which scenarios to build, what assumptions require approval, and what outputs leadership needs to compare. Ask for cash impact, hiring implications, trigger points, and a sensitivity table.

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

Example:

Refresh Acme’s FY27 forecast for the Enterprise business. Use “FY27 Operating Plan Model.xlsx,” “Revenue Driver Model.xlsx,” “Headcount Plan.xlsx,” “13 Week Cash Forecast.xlsx,” April actuals, approved planning assumptions in “FY27 Planning Assumptions,” and leadership notes from #fy27-planning.

Create base, downside, and upside scenarios with the key revenue, margin, hiring, and cash drivers. Summarize cash impact, hiring implications, trigger points, and your recommendation. Include a sensitivity table and list assumptions that need approval before the plan is shared. Do not overwrite business assumptions without flagging them for review.
