Datasource: csv
CSV sources can read a URL or a file in Nextcloud Files. The final selected column is the numeric value; add a constant such as 1 when the input does not contain a numeric measure.
- URL for External CSV, or select a file for Local CSV
- Header row: turn it off when the first row is data
- Ignore leading rows for metadata before the CSV content
-
Select columns: use one-based column numbers, for example
1,2,4; non-numeric entries create constant columns
Use a source directly for real-time reports or configure it as a data load for stored data. The Nextcloud server, not the browser, retrieves external URLs; see local-network URL guidance.
The sample file is available at https://raw.githubusercontent.com/Rello/analytics/master/sample_data/sample1.csv.
For a constant first column followed by columns 1, 2, and 4, use Income,1,2,4.
