PowerPoint Comments Extractor
Drop a .pptx with reviewer comments and pull them all into one sortable table — slide, author, date, text. Export as TXT, CSV, Markdown, or JSON.
Why Extract Comments?
When a reviewer hands back a .pptx with comments scattered across slides, you typically have to click slide-by-slide in PowerPoint, copy each comment text, paste it into a tracking document, and lose author and date along the way. This tool reads the entire comment graph out of the file in one pass and produces a clean list you can sort, filter, and export.
Common uses:
- Pulling reviewer feedback into a project tracker (Linear, Jira, Notion).
- Auditing comment history for compliance or change-control.
- Migrating comments off a deck before sharing it externally.
- Producing a "we addressed this / we didn't" summary for the reviewer.
How It Works
A .pptx file is a zip archive. Reviewer comments are stored in one of two formats, depending on the PowerPoint version that wrote them:
- Classic comments (PowerPoint 2007 to 2019):
ppt/commentAuthors.xmlholds the authors, andppt/comments/comment{N}.xmlholds each slide's comments with author, timestamp and text. - Threaded comments (Microsoft 365):
ppt/authors.xmlholds the authors, andppt/comments/modernComment_….xmlholds each thread with its replies and whether it was resolved.
The tool opens the zip in your browser, matches each comment to the slide it sits on, in the order the slides appear in the deck, resolves author names, and builds one sortable list. Output runs through the same caps as our notes extractor (4,000 characters per comment, 200 KB in total), so an unusually large file can't break the page.
Tier-by-Tier Comparison
- Anonymous visitors: Read about the tool here. A free SlideModel account is required to use it.
- Free SlideModel account: Comments from the first 10 slides, TXT export only. 30 extractions per day.
- SlideModel Pro: Unlimited slides. All four export formats: TXT, CSV, Markdown (table), and JSON. No daily cap that matters.
Limitations in This Version
- Inline @mentions in comment text come through as plain text, not as links to the person.
- Reply chains are flattened: each reply is its own row, listed after the comment it answers.
- Classic comments have no resolved state, so they always show as Open.
After you've actioned the feedback
With comments captured cleanly, the next step is usually a redesign pass on the slides themselves — addressing reviewer notes about visual hierarchy, density, or pacing. Starting from a well-structured template is the fastest way to fix layout issues at scale.
