FAQ
Asked first, every time.
Don't see yours here? Send us the question — a principal engineer will reply within 24 hours.
Yes. We can build automation tools that take a data feed (like a JSON payload) and generate a complete, formatted presentation deck instantly.
Yes, modern Office JS add-ins are inherently cross-platform and work seamlessly on PowerPoint for Mac, Windows, and the web.
Yes, the PowerPoint API allows us to read, insert, modify, and format text, shapes, images, and charts programmatically.
Absolutely. We can build a scanner that reviews the current deck and highlights elements that deviate from your strict corporate brand guidelines.
We utilize the Office JS API to parse complex JSON payloads, dynamically generating new slides, mapping data to specific placeholders, and auto-populating charts based on external API responses.
Yes. Our add-ins iterate through every shape and text range on a slide, comparing the used fonts, RGB color values, and logo placements against a strict JSON-based corporate brand guideline, flagging violations to the user.
We build a custom task pane containing a React frontend that authenticates with your Digital Asset Management (DAM) system. Users can search assets in the pane and insert them directly into the slide as base64 images.
Currently, the Office JS API has limited native support for directly manipulating the internal properties of 3D models. For deep 3D manipulation, OpenXML generation or legacy VSTO may still be required.
Absolutely. The add-in can iterate through all slide shapes and speaker notes, extract the text, securely transmit it to an API like DeepL or Google Translate, and inject the translated text back into the exact original formatting.
We optimize performance by suspending screen updating during generation, utilizing `context.sync()` efficiently in batches, and ensuring images are compressed on the server before being sent to the client via base64.
