Save-code length precheck
The saves wiki says spaces and line breaks are ignored, a code over 1,000,000 characters is rejected, and a cut or mistyped code comes back as damaged. Hardcore cannot be exported. I built the box below to count characters after stripping whitespace. It does not decode the code. No public format specification was found in the sources checked, and a length check cannot detect a damaged, truncated or invalid code.
What to do with the result
If the stripped length is under the cap and the text is not empty, open SAVES in the browser game or the desktop app and paste there. The game's preview is the real check. If you were sent the code by someone else, treat it as untrusted. An edited code can load and still be barred from the ladder.
Questions and answers
Why will it not show my items?
Showing items would mean we understand the format. The wiki does not publish the format. Import in the game instead.

Source scope: the official site, FAQ, wiki and changelog share one publisher. Build IDs, installer sizes and detailed mechanics are single-source official claims unless a separate independent reference is identified. Several official links do not count as independent confirmation.
