CSVFileToArray

CSVFileToArray>CSVFile,ArrayVariable

Reads the given CSV file into a multi-dimensional array.  

The array takes the format:

arrayname_row_col

arrayname_row_count

arrayname_count

E.g. the following CSV data will produce the array variables given below:

CSV Data:

ID,Date,Value

1,28/02/2010,50

2,01/03/2010,75

Code:

CSVFileToArray>c:\myfile.csv,csvData

Array:

csvData_1_count=3

csvData_1_0=ID

csvData_1_1=Date

csvData_1_2=Value

csvData_2_count=3

csvData_2_0=1

csvData_2_1=28/02/2010

csvData_2_2=50

csvData_3_count=3

csvData_3_0=2

csvData_3_1=01/03/2010

csvData_3_2=75

csvData_count=3

Note: The column count starts at 0.  i.e. column A is 0, and not 1.

Thus :

csvData_1_0 returns the contents of Row1 Col1

csvData_1_1 returns the contents of Row1 Col2

Note that it is also possible to read CSV file data into an array using DBQuery with a suitable CSV file connection string, but CSVFileToArray is less format sensitive and can cope with rows with different field counts. There are pros and cons to both methods.  DBQuery can retrieve the data more selectively whereas CSVFileToArray reads in the entire file.

Example

CSVFileToArray>c:\temp\test.txt,csvData

If>csvData_count>0

  Let>row=0

  Repeat>row

    Let>row=row+1

    Let>field1=csvData_%row%_0

    Let>field2=csvData_%row%_1

    Let>field3=csvData_%row%_2

    MessageModal>%field1% %field2% %field3%   

  Until>row=csvData_count
