What exactly do I get in the JSON?

A structured record with the file type and size, the number of slides, the presentation title, author, dates, and any keywords, company, or slide-specific text and properties stored in the file.

Does this edit my presentation?

No. Your deck is read only, and the result is a new JSON document you can download.

Can I convert an old .ppt file?

This tool reads the modern .pptx format. Convert older decks to .pptx in PowerPoint or LibreOffice first.

Convert PowerPoint to JSON online

Need the contents of a slide deck as data? This page converts a PowerPoint (PPTX) file into JSON so you can pipe the result into scripts, dashboards, or document pipelines.

How to convert a deck

Press Convert file.
Read or download the JSON result.

What the JSON includes

A clean record pulled from the presentation package:

Slide count and presentation format
Title, subject, author, and description
Creation and modification dates
Keywords, company, and revision number
Embedded slide text and other structured properties

No editing, no re-encoding — your original deck stays untouched.

When this is useful

Extracting titles and text from a deck for search or analysis
Feeding presentation metadata into a CMS or knowledge base
Checking slide counts and properties during review workflows
