Since nobody has replied, this must have been a trivial question/issue for me. Either way, I have figured our a way that works for me. ChatGPT helped write a python script: What the script must do We process the CSV version of WMOAreaTable.dbc row by row: Ignore Column 1 Read Column 2 (this is your WMOID source) Work with Column 12 (this is the Nameset text column used by Noggit Red) Required behavior Track numbers in Column 2 When a number appears for the first time: If Column 12 is empty → copy that Column 2 number into Column 12 If Column 12 already has data → DO NOT overwrite it If Column 12 was not empty: Continue scanning rows Ignore rows with the same Column 2 number Resume normal behavior only when Column 2 increases to a new higher value So effectively: Each unique Column 2 value is handled once Only the first row of each new Column 2 group is eligible But only written if Column 12 is empty Never overwrite existing nameset text Now I can easily backtrack the WMOIDs of all WMOs, even ones that only have a default (0) nameset. The only issue is that whenever I enter a default WMO, it displays its WMOID. But that is so easy to remore and actually revert the rows to column 12 being empty. I only needed this debug to make custom WMO zonemusic, ambience and zone names. https://cdn.discordapp.com/attachments/870722120458600528/1478840038832738486/WoWScrnShot_030426_203952.jpg?ex=69a9dc9c&is=69a88b1c&hm=cf1236482ece9a8c0e14568eed584c872474285c9021564b1accdf27edc706b0& https://cdn.discordapp.com/attachments/870722120458600528/1478840039344570461/WoWScrnShot_030426_203957.jpg?ex=69a9dc9c&is=69a88b1c&hm=9746a11089b63c57ef5834db637d48cdbe4cab59fcfa15dc1700f74c00e98f43& https://cdn.discordapp.com/attachments/870722120458600528/1478840040082903201/WoWScrnShot_030426_204003.jpg?ex=69a9dc9d&is=69a88b1d&hm=331b008b920536e9d8681ac4677969433d0a468d893e6870a4f39664b63683fa& https://cdn.discordapp.com/attachments/870722120458600528/1478840040569176275/WoWScrnShot_030426_204018.jpg?ex=69a9dc9d&is=69a88b1d&hm=5fb355c406cab3c4050ee0b5dce7ef789777a1fa9d14fbdf8435029f47d57ba3&
