Trim CSV output

[shilpamehta1991]

Hello,

Is it possible to trim only the first and the last record of a CSV output and delete all the other commas and keep delimiters?

Please find the screenshots for reference.

I'd suggest configuring your input tool to load the data with no delimiter \0 option, uncheck First row contains Field Names and set Field length to a large enough value.

The use a filter tool to remove the 1st and last line with a formula like this:

!Contains([Field1],'HDR,E,1234567') AND !Contains([Field1],'TRL,E,1234567')

Please clarify the last part of your question.

I mean I want to output a csv in which the first and the last record should not have additional , at the end. I want to trim those commas only for the first and last record.

 Please see the 2 screenshots. one is my current output with the , in the end and the other is my expectation without comma at the end.

Ah ok, now I get you.

Ok, so load the data as described into a single field with no parsing (\0). The use a formula tool with the following formula.

Let me state my requirement again.

I am outputting a csv which currently looks like below-

However I need the csv to not have additional comma in the first and the last record.  Please refer below-

Is there some way this can be done?

Okay, maybe not the most optimal way to do it, but does the attached WF solve this?

[DavidP]

Ok, perhaps I was over complicating it.

The key thing is that your data has to be in a single column as shown in the attached example. You can then get rid of the trailing commas with a trimright formula. This will remove trailing commas from ALL rows, unless you have another way to identify top and bottom records.

You can then use an Output Data tool, CSV format with no delimiter (\0) to write your output file.

If, however, your dataset is in multiple columns, you have to get it into a single column first for this to work.

No but I need to keep all the trailing commas in all my other records except the first and the last.

Is that possible?

[DavidP]

As I said, you then have to find another way to identify the 1st and last row and put it in an if statement, for instance, something like:

if StartsWith([Field1], 'HDR') or StartsWith([Field1], 'TRL') then TrimRight([Field1],',') else [Field1] endif

Have a look at my earlier post that retains the trailing commas except in the first and last record.
