Haddock to PPTM Converter
Processing entirely on your device — large files may take a moment.
Extract text and outlines from PPTM decks exactly like PPTX. If your files are still in Haddock format, this page is the shortcut: Haddock is the documentation markup of the Haskell ecosystem: -- comment blocks attached to functions, rendered into the API docs every Hackage package ships.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.
How Haddock compares to PPTM
| Haddock | PPTM | |
|---|---|---|
| Structure | Comment markup (--, 'links', @mono@) | OOXML zip: slides + media |
| Compatibility | Haskell, Hackage, Pandoc | Office 2007+, Slides, WPS |
| Best for | Haskell API documentation | Decks and slide content |

About the Haddock format
Haddock is how Haskell explains itself: documentation comments in -- blocks, marked up with 'links' to identifiers, @monospace@ and /italics/, compiled into the API reference pages every package on Hackage publishes. The markup lives inside source files, but the format is its own small language.
Converted out of source comments, Haddock text becomes ordinary structured prose: Pandoc maps headings, code blocks and identifier links onto Markdown or HTML, so API knowledge can move into handbooks, wikis or static-site generators without retyping.
+Strengths
- ✓Documents live next to the code they describe
- ✓Identifier-aware linking across the API
- ✓Standard for the entire Haskell ecosystem
!Limitations
- −Meaningful only inside Haskell projects
- −Small grammar, few writers outside Haddock itself
- −Embedded in comments — needs extraction first
About the PPTM format
PPTX is the modern PowerPoint deck: a zip of XML parts describing slides, shapes, text runs and media. That structure is exactly why text can be extracted faithfully without PowerPoint — every word on every slide is in the package, with its slide number.
One honest limit: extraction is about words, not looks. Slide layouts, backgrounds, animations and images do not survive a text export — the output is the content of the deck, not a picture of it.
+Strengths
- ✓Text and slide order preserved exactly
- ✓Opens in PowerPoint, Keynote, WPS, Slides
- ✓Zip+XML structure is machine-friendly
!Limitations
- −Text export loses layout and visuals
- −Charts and tables flatten to text
Why convert Haddock to PPTM?
Converting makes sense where the strengths of PPTM meet what Haddock cannot give you. Text and slide order preserved exactly Meanwhile Meaningful only inside Haskell projects One pass through the converter above puts your file on the right side of that trade-off.
Frequently asked questions
Is this Haddock to PPTM converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for Haddock to PPTM?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Does the conversion include images and backgrounds?
No. This is a text extraction: words on slides survive, layouts, backgrounds, animations and pictures do not. Keep the original deck for the visuals.
Will Haddock to PPTM keep the slide order?
Yes — slides are read from the file in their real order and numbered, so the output follows the deck exactly.
