This usually happens because export from a Power BI visual has limits or changes behavior during export.
Check these common causes:
- Export limit was hit
- For
.xlsx, a table visual can export up to 150,000 rows. - For
.csv, the limit is 30,000 rows. - If the limit is hit, Power BI can omit some data.
- In Excel, check whether the exported file shows the message: "Exported data exceeded the allowed volume. Some data might have been omitted."
- For
- DirectQuery reduced the exported result
- If the report uses DirectQuery, export is also limited to 16 MB uncompressed.
- That can cause fewer rows to be exported than expected, especially when there are many columns or data that does not compress well.
- Try reducing the number of columns in the visual, then export again.
- Show items with no data affects export behavior
- When exporting summarized data, Power BI converts the visual to a table during export.
- That can change the exported result compared to what is shown in the visual.
- If Show items with no data is enabled, turn it off for the fields in the visual and export again.
- Underlying data export may be blocked by model conditions
- Export using Underlying data does not work if:
- the model tables do not have a unique key
- an admin or report designer disabled the feature
- Show items with no data is enabled for the visual
- Export using Underlying data does not work if:
- Multiple tables without an active relationship
- If the visual uses data from more than one table and there is no active relationship between those tables in the model, Power BI exports data only for the first table.
- This can make rows appear missing in Excel.
To resolve it, try this order:
- Export to .xlsx instead of
.csv. - In the visual, remove unnecessary columns and export again.
- Turn off Show items with no data for the fields used in the visual.
- If available, compare Summarized data versus Underlying data export.
- If the visual uses fields from multiple tables, verify the data model has an active relationship between those tables.
- If the dataset uses DirectQuery, expect fewer exported rows and simplify the visual before exporting.
- If export is missing, grayed out, or still incomplete, ask the report owner or Power BI admin to check whether export is disabled or restricted.
If the issue is only for one CNIC and Power BI shows 16 rows while Excel shows 10, the most likely causes are:
- Show items with no data changing the export result
- no active relationship between tables used in the visual
- DirectQuery/file-size export reduction
