How to insert several csv files into Elasticsearch?

I have several csv files on university courses that all seem linked by an ID, that you can find here , and I wondered how to put them on Elasticsearch. I know, thanks to this video and Logstash, how to insert one sole file csv file to Elasticsearch. But do you know how to insert several such as those in the provided link ? At the moment I started with a first .config file for a first csv file : ACCREDITATION.csv. But it would be painful to write them all... The .config file is : input{ file{ path =>"Users/mike/Data/ACCREDITATION.csv" start_position => "begining" sincedb_path => "/dev/null" } } filter{ csv{ separator => "," columns => ['PUBUKPRN', 'UKPRN', 'KISCOURSEID', 'KISMODE', 'ACCTYPE', 'ACCDEPEND', 'ACCDEPENDURL', 'ACCDEPENDURLW'] } mutate{convert => ["PUBUKPRN","integer"]} mutate{convert => ["UKPRN","integer"]} mutate{convert => ["KISMODE","integer"]} mutate{convert => ["ACCTYPE","integer"]} mutate{convert => ["ACCDEPEND","integer"]} } output{ elasticsearch{ hosts =>"localhost" index =>"accreditation" document_type =>"accreditaiton keys" } stdout{} } ###Update May, 3rd Without knowing how to use a .config file to implement csv files to Elasticsearch, I fell back to Elastic blog and tried to do a shell script importSVFiles for a first .csv file before trying to generalize the approach : ###importCSVFiles : #!/bin/bash while read f1 do curl -XPOST 'https://XXX.us-east-1.aws.found.io:9243/courses/accreditation ' -H "Content-Type: application/json" -u elastic:XXX -d "{ \"accreditation\": \"$f1\" }" done < AccreditationByHep.csv Yet I received a mapper_parsing_exception on the terminal : mike@mike-thinks:~/Data/on_2018_04_25_16_43_17$ ./importCSVFiles {"error":{"root_cause": [{"type":"mapper_parsing_exception","reason":"failed to parse"}], "type":"mapper_parsing_exception", "reason":"failed to parse", "caused_by":{"type":"i_o_exception","reason":"Illegal unquoted character ((CTRL-CHAR, code 13)): has to be escaped using backslash to be included in string value\n at [Source: org.elasticsearch.common.bytes.BytesReference$MarkSupportingStreamInputWrapper@e18584; line: 1, column: 88]"} },"status":400 }
