CSV file help

Joseph Alotta
Greetings,

I am needing conceptual help with parsing these troublesome CSV files.  I was breaking the lines using String >> findToken:
but I found lines where extra deliminators were added.  Notice the three following lines, the first and third line have extra commas from Oak Brook, IL and the second line does not have the comma.


02/04/2016  Thu,,"COSTCO WHSE #0388 000000000990388 - OAK BROOK, IL",,,,,37.00,,,,,,,,
02/05/2016  Fri,,"ELECTRONIC PAYMENT RECEIVED-THANK",,,,,-443.52,,,,,,,,
02/06/2016  Sat,,"COSTCO WHSE #1088 000000000991088 - BOLINGBROOK, IL",,,,,50.86,,,,,,,,

I think I need to parse with the double quotes in mind, but I don’t know where to break it.

Also, I was reading in the squeak pages that someone had already written code for this, but I couldn’t find anything.

http://wiki.squeak.org/squeak/3260 has two methods, CSVSubstrings and SequenceableCollection-asCSVLine.st

Does anyone know where these are now?

Sincerely,

Joe.

Hi Joe,

I haven't tried it but I would probably start with Avi's CSV Parser
http://www.squeaksource.com/CSV.html

But in general you want to parse all of your lines, then for each line parse quoted values, then you can parse commas.

All the best,

Ron Teitelbaum

I tried to download it, but the .mcz file could not be read.

I also tried pasting

MCHttpRepository
    location: 'http://www.squeaksource.com/CSV'
    user: ''
    password: ‘'



Into a workspace and evaluating it and it does nothing.

Can you provide instructions, please?

Sincerely,

Joe.

Hi Joe,

 

World menu> open… > Monticello Browser.

 

Press the +Repository button and select HTTP.

 

Paste in the Repository location

 

MCHttpRepository
    location: 'http://www.squeaksource.com/CSV'
    user: ''
    password: ‘'

 

accept and then select open.

 

Select the latest version and press load.

 

Monticello is a key component to managing an image.  You should definitely read up on it.

All the best,

Hi Joseph,
these methods are now in the package located at:
MCHttpRepository
location: 'http://www.squeaksource.com/CSVData'
user: ''
password: ''
(follow Ron's excellent advice on how to use this).

That said, I would no longer use this package to parse CSV - I've recently switched over to Avi's parser as well.
(My package still has some interesting uses for the data once you pull it in.  Of course, it isn't documented.)

I should clean up the page that you found - I had forgotten that it even existed!

Hello Joseph, maybe

for example:

data add: '02/05/2016  Fri,,"ELECTRONIC PAYMENT RECEIVED-THANK",,,,,-443.52,,,,,,,,' copy. 
data add: '02/06/2016  Sat,,"COSTCO WHSE #1088 000000000991088 - BOLINGBROOK, IL",,,,,50.86,,,,,,,,' copy. 
data do:[ :item |
        fields := item findTokens:',' escapedBy: '"'.
        "show result in Transcript"

Rudolf,

That is perfect!  Thank you so much.  I love the simple yet elegant solutions.

I tested it with the large file and it works great.  And best of all, it is included in the basic system.

Sincerely,

Joe.
