To import 15 or 30-minute data (e.g. half-hourly data):

- go to "Data - Add data - Import data",

- focus on the "Import half-hourly file" box

- configure the file format (e.g. file structure, columns order, start data row and date format)

- select your CSV file

- and press "Submit".

The reading values must be number formatted with no thousands separator.

Both point (".") and comma (",") can be used as a decimal separator. This is set up in the user account settings.

Data must be uploaded using valid CSV files (i.e. only comma/semicolumn delimited files for each column).

Importing half-hourly files might take a while. Please make sure to keep your computer on with an active internet connection at all times.

A "success" notification will appear at the end of the import. If you miss it, using your 'go back' browser feature should make it appear again.
