In my dataset, the data which contains house numbers are converted to date format in QGIS. Is there any script or tool to identify and convert them to normal format?

E.g. Case:

Actual Door No format is 11-10-60 and converts to Date format 11/10/1960

How can we identify the date format in the list of data and convert it back to the actual door no format?

    To be clear: from a field house number, you want to convert the values to a date format which matches your example., am I right? Do the house numbers have a similar format to this one 'xx-xx-xx' ?

    I guess its a CSV? Then you could just force QGIS to read this field as string.

If you import from CSV, change data type from Date to Text(string) when importing CSV.

enter image description here

Otherwise, add another field using the following expression in Field Calculator (set door number field before using).

lpad(month(door), 2, '0') || '-' || lpad(day(door), 2, '0') || '-' || right(year(door), 2)
