You're looking for a report on "Save Editor ES3". Here's what I found:

The editor presents a clean, hierarchical view of the save file. Instead of staring at a wall of hexadecimal or encoded text, users see a structured tree:

Troubleshooting common issues

• Game refuses to load edited save: restore backup, ensure checksum fix applied, verify correct save slot/filename.
• Corrupted save after edit: try previous backup or use hex editor to revert known sections.
• Values not reflected in-game: some games cache progress server-side or use encrypted fields; local edits may be ineffective.
• Editor crashes opening a save: ensure latest version of the editor and that the save format is supported.

3.2 Modification

• Locate specific record (e.g., NPC_ for player actor, CONT for container, QUST for quest).
• Overwrite field values (gold, health, perk count) – often requires checksum/hash recalculation.
• For inventory: modify CNTO subrecords (item FormID + count).

Step 7: Test in Game Load your save. If the game crashes or shows weird behavior, revert to your backup and try a smaller edit.

, which allows you to upload a file, modify keys, and download the edited version. Game-Specific Editors
