Features
No Node, no npm install
The runtime lives on our servers. You paste a script and get a file back — nothing to install, no package.json, no version conflicts with your local toolchain.
Real execution, not a preview
Your script runs against the actual PptxGenJS library, so addSlide, addText, addChart, addTable, addImage and addShape all behave exactly as they would locally.
Charts and tables come through as native objects
A chart defined with addChart lands in the deck as an editable PowerPoint chart, not a flattened picture — same for tables, shapes and grouped elements.
Automatic repair of common script errors
Missing writeFile calls, ESM/CommonJS import mismatches, stray markdown fences from an AI answer, and hallucinated helper names are detected and corrected before the run.
Instant slide previews
See every generated slide rendered in the page before you download, so you can catch a layout mistake and re-run without opening PowerPoint.
Run a PptxGenJS script online and download the PowerPoint it generates. Paste your JavaScript into the editor and the script executes server-side against the real PptxGenJS library — there is no Node runtime to install, no npm install pptxgenjs, and no local project to scaffold just to test one deck. This is the fastest path when an AI assistant has written you a deck script and you have nowhere to run it, when you are prototyping slide layouts and do not want a build step between each attempt, or when you are on a machine where installing a toolchain is not an option. Everything the library supports works: addSlide, addText, addTable, addChart, addImage, addShape, master slides, speaker notes and custom layouts. Charts and tables arrive as native, editable PowerPoint objects rather than images. Before the run we quietly fix the errors that break most pasted scripts — a missing writeFile, mismatched import style, leftover markdown fences, or an invented helper function — then render every slide as a preview so you can check the result before downloading. Try without sign-up.

Frequently Asked Questions
Which PptxGenJS version does the sandbox run?
A current 3.x release, which is what almost every published example and AI-generated script targets. Scripts written against the 3.x API run unchanged; very old 2.x-era snippets may need their option names updated.
Do I need to call writeFile at the end of my script?
It helps but is not required. If your script builds a presentation object and never writes it, we detect the finished object and save it for you. If you do call writeFile or writeFileSync, we capture that output instead.
Can my script fetch images or data from a URL?
Remote images referenced by https URL are fetched during the run. Arbitrary network calls to internal or private addresses are blocked for security, so build your deck from inline data or public image URLs.
Are charts real PowerPoint charts?
Yes. A chart created with addChart is written into the file as a native chart part, so you can click it in PowerPoint and edit its data series. The same applies to tables created with addTable.
My AI assistant wrote the script. Will it run as-is?
Usually. The most common failures in AI-written scripts are a missing save call, a mix of require and import syntax, markdown code fences copied along with the code, and helper functions that were never defined. All four are repaired automatically before the run.
What happens if my script throws an error?
You get the actual error message and the line it came from, not a generic failure. Fix the line and re-run in the same editor — the script stays in the box between attempts.
