Repairing a PPTX File

PPTX File Header Data

PPTX files contain a sequence of unique bytes at the beginning of the file. This header section is usually followed by the main PPTX file section. Where the header block is present, our document repair tool will parse the header data to validate the file type and also provide additional metadata that describes key characteristics of the document uploaded.

Microsoft Office Documents

Microsoft Office formats such as PPTX are actually compressed container formats using the ZIP format as the underlying container. The data for these documents is stored in XML format. With this knowledge, our PPTX tool parses these documents to ensure the underlying XML is correctly formatted.
