#   It may be necessary to remove the second line, before running.
#   It may be necessary also, to change the currency symbol if your file
#   includes one.
#
#   Simple utility to convert a csv format file, as from a bank, to qif
#   format for KMyMoney2.  There is no standard for the layout of such a
#   file, but generally there will be a header line which indicates the
#   layout of the fields within the file.  Even then though, the order of
#   the columns may vary.  It is assumed, though, that the first column
#   will contain the date, in 'dd MM yy' format, 'MM' being the month
#   name or number.
#   The  second column is the detail.  The third and fourth columns are
#   assumed to be debits and credits.  Even fron the same bank, these
#   columns may be reversed, but the script handles this.  Alternatively,
#   the third column may be the amount.  There may also be additional
#   columns, such as current balance, but these are all ignored.
#   Apart from the header line, there are likely to be other lines, with
#   account number, balance details, etc.  These are skipped.
#
#   First, make the script executable: chmod u+x csvbankinyqif.py .
#   The script should be added to the KMM QIF import profile.  In KMM, open
#   Tools/QIF Profile Editor and click on 'New' at the bottom.  then enter a
#   name, such as csvbank, then click 'OK'.  Next, click on that name in the
#   next window, and open the Filter tab.  For the 'Input filter location',
#   select the location you chose for the script file.  For the Input filter
#   file type, enter *.csv, or whatever extension your data file has.
#   Finally, click 'OK'.
#   When ready, select File/Import/QIF, and browse to your data file, then
#   select your new filter profile, and click 'Import'.
