How can I set the title of a QGIS map based on a name I pass in a .csv file?

I create a separate file 'tombstone_data.csv' that contains two fields like this:

FlightRadar24,1 x per 3 sec

however I cannot find out how to use the source field (= 'FlightRadar24') as the title of the map.

  • have you imported the CSV as a table in the map, or are you trying to read it from file?

  • imported the CSV as a table. Could as well read it from a file if that is easier. Commented Jan 29, 2022 at 13:12

You can use an expression for the Label item text.

enter image description here

Then use:

attribute(get_feature_by_id('myCsvLayer', 1), 'source')

It finds the attribute value from the feature with id=1 in the source field of the layer called myCsvLayer.

You will see that once you click OK the label text is wrapped in [% %]. This is so it evaluates as an expression.

[%attribute(get_feature_by_id('myCsvLayer', 1), 'source')%]

enter image description here

If you want to identify a feature using an attribute value (like a unique code that exists in your attribute table) use get_feature rather than get_feature_by_id:

attribute(get_feature('myCsvLayer', 'fieldName', 'fieldValue'), 'source')


I noticed when I was testing that if you add a CSV via Layer > Add Layer > Add Delimited Text Layer the feature id starts at 2 which I think must be a bug.

A CSV layer added by dragging it directly into the map canvas starts at 1.
