Use this interactive demo to learn how to switch PowerPoint's proofing language for spell check.

Quick summary

Changing the proofing language in PowerPoint ensures spell check catches errors in the correct language for your presentation. This setting is found under the Review tab and applies instantly once confirmed with OK.

Steps

Inside the slide canvas of your PowerPoint presentation, go to the top menu bar and click 'Review'.
Find and select 'Language' in the ribbon.
Under the Slide tab, select the language you wish to use.
Tap 'OK' to apply the changes.
The proofing language of your PowerPoint presentation for spell checking will be updated based on your selection.

📌 Why this matters

Setting the correct proofing language in PowerPoint is essential for accurate spell checking across multilingual presentations. Without this configuration, PowerPoint may flag correctly spelled words as errors or miss genuine mistakes in non-default languages. This feature is especially valuable for global teams and international content creators who work across multiple languages. Knowing how to change the PowerPoint language setting ensures polished, error-free presentations every time.
