Wrong MYSQL format number in Google Sheets via JDBC - mysql

Question

The numbers that I import from an sql database on google sheet are interpreted as duration and not as numbers, more specifically as currencies.
colA
colB
colC
colD
449
1234
29521.00
0.00
449
1234
29521.00
0.00
Wrong = 29521.00 (format currently imported)
Correct = € 29.521,00
What am I doing wrong in colC and colD?

The fact that the values get automatically converted to durations suggests that the data is in a format that makes Google Sheets consider them as duration values. This can happen if you read and write the data as text strings and your spreadsheet is in a locale that uses commas as decimal separators (as in € 1,99) and periods as time separators (as in 12.00). If you are reading the values as text strings, you may need to read them as numbers instead to avoid automatic conversion.
Consider using ResultSet.getFloat() instead of ResultSet.getString().
Once you can write the values correctly to the spreadsheet, you can set the final format programmatically, like this:
SpreadsheetApp.getActive()
.getRange("Sheet1!C2:D")
.setNumberFormat("[$ €]#,##0.00");
If you always write the values to the same sheet, and get the data as numbers from the database, you can most likely manually format columns C:D as Format > Number > Currency just once, and have the format stick through future imports.
