elasticsearchHow can I export data from Elasticsearch to a CSV file?
Exporting data from Elasticsearch to a CSV file can be done using the Elasticsearch-CSV library.
The library provides a command line tool called es2csv
that can be used to export data from an Elasticsearch index to a CSV file.
For example, the following command can be used to export data from the my_index
index to the my_data.csv
file:
es2csv -u http://localhost:9200 -i my_index -f my_data.csv
The command above will export all fields from the my_index
index to the my_data.csv
file. If you want to export only specific fields, you can use the -f
option to specify the fields to be exported.
For example, the following command will export only the title
and date
fields from the my_index
index to the my_data.csv
file:
es2csv -u http://localhost:9200 -i my_index -f my_data.csv -f title,date
If you need to export data from multiple indices, you can use the -i
option to specify the indices to be exported.
For example, the following command will export all fields from the my_index_1
and my_index_2
indices to the my_data.csv
file:
es2csv -u http://localhost:9200 -i my_index_1,my_index_2 -f my_data.csv
The library also provides a Python API that can be used to export data from Elasticsearch to a CSV file programmatically.
