The problem
The only way to see how localized ad copy would actually render on the XBOX console was to go into console settings, change the language, and reboot, then do it all again for the next one. Spot-checking one or two languages that way was fine, but covering 20 or so took far too long. So copy that looked fine in English could run past its character limit in German or Greek, and those catches often came too late.
The approach
The tool started with a question I asked myself. How could I preview all of our localized content, know exactly how it would render, and see it on one page I could save if needed? There was no complete spec, so working with Copilot, I created a custom HTML page from real ad placements, comparing it against the console and refining the layout until it matched almost pixel for pixel. The page rendered every supported language side by side at real display dimensions and highlighted anything that exceeded its character count.
The result
A settings change and a reboot per language became one page with every language on it and the overruns already highlighted. Reviewing 20 or so languages took a single scroll, so languages that used to get skipped got checked too, and the page could be saved whenever a record was useful.
| Measure | Before | After |
|---|---|---|
| Language review | Change console language and reboot for each | Every supported language on one page |
| Copy over character limits | Often caught late | Highlighted in the preview |
