Large numbers truncated in Calc

I have a csv file where large numbers are stored. When I open the file in Calc, it somehow alters the numbers so that the trailing 7 digits are replaced by 0’s. For example, 9400111201080133911953 shows up in Calc as 9400111201080130000000. how can I fix this?


In the import window, click the column head to select it, and after select Text in the Column type.

Better than my answer

LibreOffice is recognizing the string 9400111201080133911953 as a number, but has insufficient precision to represent this number. If you can arrange to have your csv string be quoted, “9400111201080133911953”, and choose the Quoted Field as Text option when the CSV is imported, it will display all the digits in the string. Alternatively you could prepend a ’ to the string in the CSV, i.e. '9400111201080133911953, it will be recognized as text.
