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. > > > -- This message was sent by Atlassian Jira (v8.20.10#820010)
