question Using ExtractText for filtering rows with regular expression does not work in Support Questions https://community.cloudera.com/t5/Support-Questions/Using-ExtractText-for-filtering-rows-with-regular-expression/m-p/312281#M225073 I have create a data pipeline that fetches an excel file and copies it into a table in a SQL Server. I have used ExtractText processor to filter rows by using a regular expression, as from the post at <A href="https://community.cloudera.com/t5/Community-Articles/NiFi-ETL-Removing-columns-filtering-rows-changing-field/ta-p/248149" target="_blank">https://community.cloudera.com/t5/Community-Articles/NiFi-ETL-Removing-columns-filtering-rows-changing-field/ta-p/248149</A> I have validated the used regular expression at <A href="https://www.freeformatter.com/java-regex-tester.html#ad-output" target="_blank">https://www.freeformatter.com/java-regex-tester.html#ad-output</A> However, the filter produces no match and no data is written in the SQL Server. By omitting the filter, the flow works fine so the problem is clearly in the ExtractText processor. I have searched for possible hints in this and other forums with no success. Any idea what might be wrong? Below is my complete configuration, the used source data and the configured SQL table. Thanks a lot in advance! Flow: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30551i2C73C6A2128C6046/image-size/large?v=v2&px=999" role="button" title="1_flow.png" alt="1_flow.png" /> GetFile processor: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30552iA696E490EB420669/image-size/large?v=v2&px=999" role="button" title="2_get_file.png" alt="2_get_file.png" /> ConvertExcelToCSVProcessor: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30554iD97A80E0A70CE028/image-size/large?v=v2&px=999" role="button" title="3_convert_to_CSV.png" alt="3_convert_to_CSV.png" /> SplitText processor: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30555i5C0AB268A9A2777B/image-size/large?v=v2&px=999" role="button" title="4_split_rows.png" alt="4_split_rows.png" /> ExtractText processor: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30556i9D955199194565AE/image-size/large?v=v2&px=999" role="button" title="5_filter_rows.png" alt="5_filter_rows.png" /> PutDatabaseRecord processor: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30557i9383EA3B8960A70A/image-size/large?v=v2&px=999" role="button" title="6_put_DB_record.png" alt="6_put_DB_record.png" /> DBCPConnectionPool controller service: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30558i8F5F6B59296D0D12/image-size/large?v=v2&px=999" role="button" title="7_DB_Connector.png" alt="7_DB_Connector.png" /> CSVReader controller service: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30559iA07920B922573303/image-size/large?v=v2&px=999" role="button" title="8_CSV_reader.png" alt="8_CSV_reader.png" />Source data <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30560i798BF8F8E0E80E93/image-size/large?v=v2&px=999" role="button" title="9_source_data.png" alt="9_source_data.png" /> Target table: <img src="https://community.cloudera.com/t5/image/serverpage/image-id/30561iA71C73C20B502059/image-size/large?v=v2&px=999" role="button" title="10_target_table.png" alt="10_target_table.png" /> Tue, 02 Mar 2021 08:07:15 GMT BerniHacker 2021-03-02T08:07:15Z
