I am using Wikidata Query Service to get the dates of population of some places. The output gives a raw result in the format 2010-01-01T00:00:00Z (as an example). I have also retrieved the date precision of each date. The query results display the dates in 1 January 2010 format, but upon downloading the csv or tsv file, the dates are still displayed in the raw format 2010-01-01T00:00:00Z.

I would want to display the following dates based on their date precision:

if (date precision = 11), display 1 January 2010
if (date precision = 10), display January 2010
if (date precision = 9), display 2010
otherwise, just display the raw date

How can I do this, and how can I force the downloaded csv or tsv file to display the formatted dates?

SELECT DISTINCT
  ?place
  ?placeLabel
  ?population
  ?populationDate
  ?populationDatePrecision

WHERE {
  ?place p:P31 ?instanceOf.
  ?instanceOf ps:P31/wdt:279* wd:Q134390.
  
  OPTIONAL {
    ?place p:P1082 ?pop_statement .
    ?pop_statement ps:P1082 ?population;
      pqv:P585 [
                wikibase:timePrecision ?populationDatePrecision;
                wikibase:timeValue ?populationDate ].
  }
  
  minus { ?instanceOf pq:P582 ?endTime. }
  
  service wikibase:label { bd:serviceParam wikibase:language "en". }
} ORDER BY ?placeLabel
