PowerPoint for Finance Teams: Slide Master, Charts and Accessibility

A good finance presentation is consistent, easy to update from Excel and usable by everyone who receives it. Microsoft's PowerPoint documentation covers three features that help with all three: the slide master, ways of bringing Excel data into slides, and the Accessibility Checker. This post explains what Microsoft's support pages say about each, with finance-team tips clearly labelled as ours. Menus, feature names and availability vary by version and licence, so check the current Microsoft documentation for the version you use. If your slides draw on Excel reporting, our guide to financial dashboards in Excel for executive reports covers the spreadsheet side.

The slide master: one place for consistent design

Microsoft's article "What is a slide master in PowerPoint?" explains that when you want all slides to share the same fonts and images, such as logos, you can make those changes in one place, the slide master. Edits to the slide master carry through to every slide based on it, and the article says most changes are likely to be made to the layout masters linked to the slide master. Working in Slide Master view also protects the design from accidental edits by others working in Normal view.

To open it, the article says to go to the View tab and select Slide Master; the slide master is the top slide in the thumbnail pane. Each theme has several slide layouts with different placeholder arrangements, which you manage in Slide Master view and apply to slides in Normal view. The article advises editing the masters before creating slides, because changing them afterwards means reapplying layouts to existing slides.

A further point shows how versions differ: for Microsoft 365 on Windows desktop, the article says that when a presentation has 25 or more slide masters and some are unused, PowerPoint offers to remove them. The page's metadata shows a date of 11/19/2025 and an update timestamp of 2026-06-15.

Customising the master

Microsoft's article "Customize a slide master" says a slide master helps add consistency to colours, fonts, headings, logos and other styles. It lists what can be changed, including colours, fonts and effects (through the master or a theme), backgrounds (through themes), placeholders (which can be moved, hidden or shown), layouts (existing ones modified, custom ones created, built-in ones deleted), slide orientation and footers. The footer placeholders for slide number, date and footer text can be shown or hidden per layout.

The article's steps are: on the View tab select Slide Master, make the changes you need, then select Close Master View. To reuse the design, it says to use File and Save as (or Save a Copy), change the file type to a template, name it and save. It applies to PowerPoint for Microsoft 365, 2024, 2021, 2019 and 2016, and its page date is 04/20/2026.

Our suggestion for finance teams: build one house master with a small number of layouts you actually use, such as title, title and content, two content and a full-width chart layout. Put the confidentiality or draft marking in the footer of the layout instead of typing it on each slide. Treat the master as a controlled file, as you would a reporting template.

Bringing Excel data into PowerPoint

Microsoft's article "Insert and update Excel data in PowerPoint" distinguishes linked and unlinked data. Linked data from a saved Excel worksheet stays connected to the presentation, so you can refresh it when the source changes. The article covers linking a cell range by copy and paste, and linking a whole worksheet through Insert and Object. To refresh linked data, it says to right-click it and select Update Link. Unlinked, copied data does not update automatically.

The article names these paste options for a cell range: Use Destination Styles, Keep Source Formatting, Embed, Picture and Keep Text Only. In brief, Microsoft describes Embed as keeping a copy you can edit later in Excel, and Picture as a static image that cannot be edited as data. It also lists caveats:

• A large Excel file can greatly increase the size of the presentation when embedded.
• Embedding may expose more of the Excel file than intended.
• A linked worksheet object shows the active, top worksheet of the workbook, so save the workbook with the intended sheet showing first.

The article applies to PowerPoint for Microsoft 365, 2024, 2021, 2019 and 2016; its date is 02/19/2026 and its update timestamp is 2026-06-15. The documentation we read is about cell ranges and worksheets. A related Microsoft article on pasting Excel data names the same paste options. This guide does not confirm how each option behaves for charts specifically, so check the current documentation for your version before relying on a particular option for a chart.

Our suggestion: because Microsoft warns that embedding may expose more of a workbook than intended, think about who will receive the file. For a board pack that leaves your organisation, a picture of the chart or table is often the safer choice, with the live workbook kept in your own files. For an internal deck that is refreshed monthly, a link can save time, but the workbook needs to stay where the link expects it. If dashboards in Power BI are part of your reporting, our overview of Power BI for finance teams explains that tool; this post does not cover it.

Accessibility: what the Accessibility Checker covers

Microsoft's article "Make your PowerPoint presentations accessible to people with disabilities" says the Accessibility Checker runs automatically in the background and shows a reminder in the status bar when it finds issues. To run it manually, go to Review and Check Accessibility. It flags missing alt text, reading order problems, insufficient colour contrast, slides without titles, and split, merged or nested table cells. The article is explicit that it does not catch every contrast problem, such as those in transparent text boxes, placeholders over the background or non-text content, so a manual check still matters.

Alt text for charts

The article says visuals include pictures, SmartArt, shapes, groups, charts, embedded objects, ink and videos. Alt text should briefly describe the image, including its purpose and what matters about it, and should be no longer than a short sentence or two. It advises not repeating nearby text and avoiding phrases such as "an image of". It adds that PowerPoint for PC in Microsoft 365 auto-generates alt text for photos, stock images and PowerPoint icons, which you should check and edit, while charts, SmartArt, screenshots and shapes need manual alt text.

Titles, reading order, colour and tables

• Titles: each slide should have a unique, descriptive title, even if hidden, because screen reader users rely on titles to find slides.
• Reading order: screen readers read objects in the order listed in the Reading Order pane, which may differ from the visual order. Built-in layouts are designed so the order matches.
• Colour: make sure colour is not the only way information is conveyed; the article suggests testing with the Windows grayscale colour filter and says text should be readable in a high contrast mode.
• Tables: avoid tables where possible; if one is necessary, use table headers and avoid split cells, merged cells and nested tables. Blank cells can also mislead screen reader users.

The article applies to PowerPoint for Microsoft 365, 2024, 2021, 2019 and 2016, plus iPad, iPhone and Android versions. Its metadata shows a date of 04/21/2026 and an update timestamp of 2026-08-24.

Board presentation habits: our suggestions

These points are our own suggestions, not Microsoft guidance:

• Write slide titles as the takeaway ("Cash position improved against forecast") rather than a topic label, which also supports the unique, descriptive titles Microsoft recommends above.
• Show one main message per chart and say what the reader should look at.
• State the period, units and source on every chart, so a slide still makes sense when lifted into another document.
• Move supporting detail to an appendix and keep the main section short.
• Run the Accessibility Checker before circulating, and write alt text for each chart.

Frequently asked questions

Where do I edit the slide master in PowerPoint?

Microsoft's article says to go to the View tab and select Slide Master. The slide master is the top slide in the thumbnail pane, with layouts beneath it.

Should I link or embed Excel data in a presentation?

Microsoft says linked data can be refreshed when the source changes, while embedding keeps a copy in the presentation. It warns that embedding can increase file size and may expose more of the workbook than intended. Which is right depends on who receives the file.

Does the Accessibility Checker find every problem?

No. Microsoft says it does not catch contrast problems in transparent text boxes, in placeholders over the background or in non-text content, and charts need manually written alt text.

How long should alt text for a chart be?

Microsoft says alt text should be no longer than a short sentence or two, describing the purpose of the image and what matters about it.

Set up the master once, choose link or picture deliberately, and run the Accessibility Checker before every circulation.
