Lokalise supports PowerPoint presentations in PPTX format (please note that currently we do not have support for PPT or ODP files). These documents do not require any special formatting, but please note that they can only be uploaded to projects with ad hoc documents type. The project type is selected upon creation:

Please note that if your PPTX file contains different styles in a single text line, Lokalise might import such texts as separate keys. Therefore, to achieve the best import results, please avoid using different styling within the same lines of text (fonts, color, size, etc).
