## TL;DR
The export exceeded the vendor's file cap. Export in smaller segments split by date range, department, or app, then combine the segments. For recurring needs, switch to the vendor's API for paged pulls.

```text
"usage report export failed" file too large
```

## Use this when
- A usage report export fails citing size limits.
- The report works for small scopes but not the full org.
- The failure is consistent, not intermittent.

## Not for this skill when
- The export fails on auth. Fix credentials.
- The export fails halfway without a size message. That may be a network or data issue.
- The report is empty. That is a data problem, not a size problem.

## Steps
1. Note the vendor's documented export size limit. Verify: you know the cap you are working under.
2. Split the report by a natural dimension: month, business unit, or app. Verify: each segment is plausibly under the cap.
3. Export each segment. Verify: every segment succeeds.
4. Combine the segments into one dataset. Verify: the merge is clean.
5. Check row counts against expectations. Verify: nothing is missing.

## Variant phrasings
### export too large
The short phrasing.
### report download failed size
The symptom-first search.
### usage report truncated
The related symptom.

Compatibility: Any SaaS usage-report export with file-size caps.

## Why it happens
SaaS export endpoints cap file sizes to protect the service. The cap is per export, so segmentation is the intended workaround, not a hack.

## Edge cases / pitfalls
- Segments that are still too large; split further along a second dimension.
- CSV row limits in the tool used to open the result; the file may be fine while the viewer chokes.
- Segments exported at different times showing inconsistent snapshots; export quickly or accept the skew.
- Headers differing between segments; normalize before combining.
