I was trying to get a csv file to fill a list of lists in an AS Studio project.
I have this:
--get the csv file
set slFile to ((path to library folder from user domain) & "test.txt") as Unicode text
set tempData to read file slFile
--save the ASTIDs
set ASTID to AppleScript's text item delimiters
--make them a comma
set AppleScript's text item delimiters to {","}
--clear the list
set MyList to {} as list
--repeat thru the text by paragraph
repeat with aLine in (paragraphs of tempData)
set itemList to {} as list
repeat with aItem in (text items in aLine)
set end of itemList to aItem as list
end repeat
set MyList to (MyList & itemList) as list
end repeat
This makes one list with the items or {item1A, item2A, item1B, item2B, etc}
What I am trying for is {{item1A, Item2A}, {item1B, item2B}, etc}
I guess you have to change the second to last line of your code:
set MyList to MyList & {itemList}
Here is another piece of example code I made up for you:
set textlist to {"Here I go again!", "Let's have a party!", "Don't worry about the future!"}
set matrix to {}
repeat with textstring in textlist
set wordlist to {}
repeat with textitem in (text items in textstring)
set wordlist to wordlist & textitem
end repeat
set matrix to matrix & {wordlist}
end repeat
I have code that works but was thinking that this could get awfully slow if the CSV file was quite large. Here’s the code as it sits…
on makeList(txtData)
--save the current delimiters
set ASTID to AppleScript's text item delimiters
--reset them to commas
set AppleScript's text item delimiters to ","
--reset the tempList
set tempList to {} as list
--start paragraph loop
repeat with aLine in (paragraphs of txtData)
--reset the item list
set itemList to {} as list
--start the item loop
repeat with aItem in (text items of aLine)
--add an item by commas
set end of itemList to aItem as list
end repeat
--add item list to the end of main list
set end of tempList to itemList
end repeat
--return the list
return tempList
end makeList
Posted here with comments as that I had not seen anything like this posted here before. This maybe because of the search restrictions that ignored looking for “CSV” or my own impatience in combing through the results to find a gem.
This routine is given the data read from the CSV file as text. It returns a list of lists. While this is exactly what my intentions were, I was wondering if anyone else had come up with something faster??
I have other methods for dealing with this so that it does not negatively impact the user experience, but it might be nice.

on makeList(txtData)
set TID to text item delimiters
set text item delimiters to ","
set tempList to {}
repeat with aLine in (paragraphs of txtData)
set end of tempList to text items of aLine
end repeat
set text item delimiters to TID
return tempList
end makeList
But consider, that CSV could be more than a few items separated by commas.
What’s happening if the items contain quotes, commas or CR/LF characters ??
Thanks,
I have considered this. The CSV that I am using is controlled. There will be no extraneous data because the system that generates the file cannot handle it. I lucked out on that one.
This was indeed faster, it did not, however, make a list of lists (i.e.: {item 1A, item 2A}, {item 1B, item 2B}, etc). It made a list of multiple items.
