Daniel Stieglitz commented on NIFI-12491:
-----------------------------------------
[~iiojj2] Based on the current framework I cannot create a separate schema for
each sheet. Perhaps it only makes sense to use this header strategy when there
is on sheet in the spreadsheet.
> ExcelReader - new Schema Access strategy: Use String Fields From Header
> -----------------------------------------------------------------------

> Key: NIFI-12491
> URL: https://issues.apache.org/jira/browse/NIFI-12491
> Project: Apache NiFi
> Issue Type: Improvement
> Components: Core Framework
> Affects Versions: 1.23.2
> Reporter: Philipp Korniets
> Assignee: Daniel Stieglitz
> Priority: Major
>
> ExcelReader needs an ability similar to CSVReader to "Use String Fields From
> Header" as a Schema Access Strategy.
> Current implementation has:
> 1. Use Schema Name/Schema Text - this option relies on the order of the
> columns. Possible issues - order of the columns change, but types dont. This
> cause further calculations to be erroneous.
> 2. Infer Schema - replaces real column names with column_1,column_2 etc -
> this again loses the "context" of the column and forces us to rely on how
> columns are ordered.
> Any workarounds make workflow more complicated.
