# Excel to PowerPoint with AI: turn a workbook into a deck that makes a point > The AI builds a new deck from an Excel workbook: attach the .xlsx to a brief, and the AI reads the values of every sheet, plans the slides with you and builds tables with editable cells and charts drawn from your figures. To change a number, edit it in the Slaide editor and export the PowerPoint file again. Numbers the AI linked to workbook cells update when the workbook changes. - Source: https://ai-presentations.com/convert/excel-to-powerpoint/ - Updated: 22 October 2026 - Language: English - German version: https://ai-presentations.com/de/umwandeln/excel-in-powerpoint/ ## At a glance - Reads the values of every sheet in an .xlsx; the grid opens the first 12 sheets - Tables arrive with editable cells; the AI draws the charts from your figures - On a computer a plan comes first: one card per slide and a “What I assumed” list - Change a number in the editor and export the PowerPoint file again ## Steps 1. **Attach the workbook.** Click the paperclip in the start box and pick the .xlsx, up to 30 MB. The AI reads the values of every sheet; the grid opens the first 12 sheets. 2. **Say what the numbers must show.** Write who the deck is for, which period and unit count, and what the figures should show. The AI asks up to four questions where the brief leaves gaps. 3. **Approve the plan.** A page plan with one card per slide and a “What I assumed” list appears. Edit a card, use “Tweak it”, or approve with “Let's go”, and the slides are built and checked one by one. 4. **Edit and export.** Edit table cells and text by hand or ask in the chat for another chart, then export a PowerPoint file. To change a chart's numbers, change them in the editor and export again. ## Spec sheet | Item | Detail | Status | | --- | --- | --- | | Input | .xlsx up to 30 MB per file, 10 files at a time, read as source material. | Yes | | Sheets read | The values of every sheet. The grid, the spreadsheet view in the app, opens the first 12 sheets. | Yes | | Sheet size | Sheets up to 1,500 rows and 60 columns open as an editable grid. | Yes | | Tables | Arrive in PowerPoint as tables with editable cells. | Yes | | Charts | The AI draws them from your figures; you can move, resize, duplicate and delete them by hand. | Yes | | Changing numbers | Change a number in the editor and export again. In decks built with a workbook, numbers linked to cells update when the workbook changes. | Yes | | Credits | The free plan covers one free document. Hand edits and exports use no credits; planning, building and AI changes use credits. | Yes | The AI turns a workbook into a deck that makes a point. It reads the numbers of your .xlsx, plans the slides with you and draws tables and charts from the figures. ## What happens to an Excel workbook you attach? The workbook goes in with the paperclip in the start box, next to a brief that says who the deck is for and what it has to show. The AI reads the values of every sheet, plans the slides with you and builds tables and charts from the figures. The workbook is the material and the deck is the goal: the AI chooses the numbers that matter, writes the titles that state them and draws the chart. - **File.** An .xlsx up to 30 MB. - **Sheets.** The AI reads the values of every sheet. The grid, the spreadsheet view in the app, opens the first 12 sheets. - **Sheet size.** Sheets up to 1,500 rows and 60 columns open as an editable grid. - **Output.** Tables arrive in PowerPoint as tables with editable cells, and the AI draws the charts from the figures. The AI draws the charts itself, from the values it read. Our [guide to choosing the right chart](https://ai-presentations.com/guides/choosing-the-right-chart/) helps you decide what to ask for. Want one particular Excel chart on a slide? Attach a picture of it and name the slide. ## How do you turn a workbook into a deck? Prepare the sheet, say what the numbers must show, and check what comes back. **Steps** 1. **Prepare one sheet for the deck.** Give every row a label and state the unit and the period. Mark missing values as missing, because an empty cell should not read as zero. 2. **Name the audience, the period and the message.** “For the supervisory board: Q3 against budget, and what changes in Q4” gives the AI something to select for. “Make slides from this model” does not. 3. **Point to the sheet and the figures.** “Use the sheet Summary and leave out the working sheets” saves a round of edits. 4. **Ask for action titles.** A title that states what the numbers show, such as “EBITDA margin is 1.2 percentage points below budget because of materials”, does the explaining for the reader. The [guide to action titles](https://ai-presentations.com/guides/action-titles/) shows how they work. 5. **Approve the plan.** On a computer, the AI asks up to four questions where your brief leaves gaps, then shows one card per slide and a “What I assumed” list. If figures are missing, it may ask whether to use your real data or placeholders. The AI is instructed not to fill gaps with invented figures and to label its assumptions. Compare the figures with your workbook before you send the deck. For a monthly finance review, the [board presentation template](https://ai-presentations.com/templates/board-presentation/) and the [budget presentation template](https://ai-presentations.com/templates/budget-presentation/) show structures that work. More for the finance function is on the page for [finance teams](https://ai-presentations.com/for/finance-teams/). Your company template comes along if you open your .pptx or set up a brand; the [page on company templates](https://ai-presentations.com/ai-presentation-company-template/) explains how. ## How do you change the numbers after the first build? Two routes let you change a number after the first build: - **Change a number and export again.** To change the numbers of a chart or a table, change them in the editor and export the PowerPoint file again. In a table you can type a changed value straight into the cell. - **Linked cells.** When a deck or report uses a calculation, the AI builds the pages together with a workbook. Numbers on pages that the AI linked to cells update when the workbook changes. After the first build, change one input and see which numbers move. ## What should you check before the numbers go to the board? **Key takeaways** - **Figures.** Compare every number on the slides with the workbook, including units and periods. - **Totals.** Check that totals, shares and changes still add up after rounding. - **Assumptions.** Read the closing message in the chat: it names the material assumptions. - **Tables.** They arrive with editable cells; type a changed number straight into the cell. - **Charts.** The AI draws them from your figures. To change the numbers, change them in the editor and export again. - **Fonts.** Open the exported file once on the presenting laptop to see the deck as your audience will. ## What does PowerPoint offer for Excel data? PowerPoint itself can paste a range onto a slide. As of October 2026, Microsoft's page lists these paste options: Use Destination Styles, Keep Source Formatting, Embed, Picture and Keep Text Only. Microsoft also warns that embedding a large workbook can greatly increase the file size and give others more access to the Excel file than you intend. PowerPoint can also link a saved worksheet: Insert, Object, Create from file, Browse, tick Link, OK. Right-click the object and choose Update Link to refresh it. Microsoft notes that the object shows all data of the active, top worksheet. Details: [Insert and update Excel data in PowerPoint](https://support.microsoft.com/en-us/powerpoint/insert-and-update-excel-data-in-powerpoint). ## Brief for the AI A complete brief for the AI. Replace the [placeholders] with your facts. ```text Turn the attached Excel workbook [file name, for example our Q3 finance model] into a [8]-slide presentation for [audience, for example the supervisory board]. Goal: [what the audience should understand or decide]. Use the sheet [sheet name] for [the figures that matter, for example revenue, EBITDA and cash by quarter]. Give every slide an action title that states what the numbers show, and name the unit and period on every table and chart. Take every figure from the workbook; where a figure is missing, mark it as an assumption instead of inventing one. Show [two or three] charts and one table with [the key lines]. Leave out [sheets to skip, for example the working sheets]. Style: [our company template, or clean and corporate], 16:9. ``` [Open this brief in the editor](https://app.slaide.de/registrieren?prompt=Turn+the+attached+Excel+workbook+%5Bfile+name%2C+for+example+our+Q3+finance+model%5D+into+a+%5B8%5D-slide+presentation+for+%5Baudience%2C+for+example+the+supervisory+board%5D.+Goal%3A+%5Bwhat+the+audience+should+understand+or+decide%5D.+Use+the+sheet+%5Bsheet+name%5D+for+%5Bthe+figures+that+matter%2C+for+example+revenue%2C+EBITDA+and+cash+by+quarter%5D.+Give+every+slide+an+action+title+that+states+what+the+numbers+show%2C+and+name+the+unit+and+period+on+every+table+and+chart.+Take+every+figure+from+the+workbook%3B+where+a+figure+is+missing%2C+mark+it+as+an+assumption+instead+of+inventing+one.+Show+%5Btwo+or+three%5D+charts+and+one+table+with+%5Bthe+key+lines%5D.+Leave+out+%5Bsheets+to+skip%2C+for+example+the+working+sheets%5D.+Style%3A+%5Bour+company+template%2C+or+clean+and+corporate%5D%2C+16%3A9.&utm_source=ai-presentations.com&utm_medium=referral&utm_campaign=converter%3Aexcel&utm_content=markdown) ## Frequently asked questions ### Can AI convert Excel to PowerPoint? Yes, as reading and rewriting rather than file conversion. An AI presentation tool reads the values of every sheet in an .xlsx and builds a deck with tables, charts and titles that state what the numbers show. Check every figure against the workbook before you present. ### How do I get Excel data into PowerPoint? Attach the .xlsx to a brief: the AI reads the values of every sheet and builds tables and charts from them. As of October 2026, PowerPoint itself can link a saved worksheet as an object (Insert, Object, Create from file, Link) and refresh it with Update Link. ### How do tables and charts arrive in PowerPoint? Tables arrive as PowerPoint tables with editable cells. The AI draws the charts itself from the values it read, and you can move, resize and delete them by hand. To change a chart's numbers, change them in the editor and export again. ### Which Excel files can I attach? An .xlsx up to 30 MB, 10 files at a time. The AI reads the values of every sheet, and the grid opens the first 12 sheets. Sheets up to 1,500 rows and 60 columns open as an editable grid. ### What happens to confidential financial data? Files are stored in the EU. When AI builds or changes a deck, the request and the content it needs go to language-model providers in the USA, and use for training is excluded by contract. With confidential figures, check first whether processing in the USA is permitted for you. ## Related pages - [AI presentations for finance teams](https://ai-presentations.com/for/finance-teams/): How finance teams use AI for board packs, monthly reporting and budget decks: Excel in, waterfall bridges drawn, numbers linked to cells, models built. - [Budget presentation](https://ai-presentations.com/templates/budget-presentation/): A budget presentation template with 8 slides: summary, assumptions, income statement, EBITDA bridge, capex, sensitivity and the decisions you need. - [Board presentation](https://ai-presentations.com/templates/board-presentation/): A board presentation template with the 8 slides a quarterly board meeting needs: summary, KPIs, revenue, EBITDA bridge, initiatives, risks and decisions. - [Choosing the right chart](https://ai-presentations.com/guides/choosing-the-right-chart/): Which chart fits which message: bars to compare, lines for trends, a waterfall for bridges.
