             Summary: ExcelReader - empty files with footer
                 Key: NIFI-16336
                 URL: https://issues.apache.org/jira/browse/NIFI-16336
             Project: Apache NiFi
          Issue Type: Bug

            Reporter: Philipp Korniets
         Attachments: TestBook_20261109.xlsx,

ConvertRecord  with ExcelReader with below setup:
sheetName=Valuation
startingRow = 5
Expect - either no flowfile to be generated or flowfile with full header row 
and some value in the 3rd row in ID field.

However it skips all the headers except ID - because this is the only field 
which has value within 10 rows. (Row Evaluation Strategy)

This behaviour breaks downstream processes like queryRecord which relies on 
presence of certain fields.

There is a workaround to check the schema etc... but its different from the 
behaviour we had in ConvertExcelToCSV  processor.
