Fix exportdata.ts

exportdata.ts is currently fully commented out, we need to find the issue and decided whether it is worth it to fix this or remove it

Start by locating exportdata.ts and reading its surrounding references to determine why the file is fully commented out. Check whether it is imported or used elsewhere, then document whether it should be repaired or removed; the work is done when that decision is supported by the repository’s current usage.
