Regional settings and decimal separator RRS feed

  • Question

  • I use Excel 2010 vba code to read .txt files and make some calculations afterwards.

    The problem I have faced is that once, I have changed regional settings from Danish to UK, numbers that are imported to Excel sheet became Integer... No separator at all...

    This is how line of numbers looks like in text file:

    2015-09-28 11:20:30;174,4165;8;17,94556;17,94556;61,86356;29,52779;4974;1240,5;

    The same number should appear on Excel sheet disregard the regional settings.

    Does anybody know, how can I fix that problem?

    Thank you!

  • Not sure how you are importing your text files but in systems where the decimal separator is a dot probably best to replace the commas with dots and then possibly the semicolon separators with commas (though you may be able to specify the semicolon separator when importing).

    If not sure of the system's decimal separator you can check with

  • There is my code for importing text files... However, I haven't developed it entirely by myself, therefore I am a bit lost...

    Maybe you can come you with some idea?

  • There's a lot going on there and difficult to work out what's going on without knowing several other things including a sample of the text file. But just a guess try

    In Function ReadCSV first change the variable declared as Line to say arrLine, because Line is a keyword, then add the new line as indicated to change any commas to a a dot

      ReDim Data(0 To UBound(Lines), 0 To UBound(arrLine))
      For i = 0 To UBound(Lines)
        arrLine = Split(Lines(i), FDelim)
        For j = 0 To UBound(arrLine)
          'Parse the fields
          arrLine(j) = Replace(arrLine(j), ",", ".") ' << new line
          If IsNumeric(arrLine(j)) Then
            Data(i, j) = CDbl(arrLine(j))
            Data(i, j) = arrLine(j)
          End If

    alternatively this might also be OK

      'Split into lines
      Lines = Split(Buffer, LDelim)  ' << new line
      Lines = Replace(Lines, ",", ".")

    Obviously you will only want to do that if the decimal separator is a dot in the user's system.

    How many other places have you posted your question?
