I am attempting to map a csv file to one of my bases via scripting due to some pre-processing I would like to do, however, I began running into issues with parsing. Figuring that I had made a mistake I created a new script to test a more simple csv with state names and regions essentially hoping I could troubleshoot on my own.
This is the output table I get with an csv I upload:
And here’s the script I’m using:
// Prompt for a file upload
let csvFileResult = await input.fileAsync(
'Upload a CSV file',
{allowedFileTypes: ['.csv'], hasHeaderRow: true}
);
//Display table w/ parsed contents
let csvRows = csvFileResult.parsedContents;
output.table(csvRows)
I’ve been looking at the spreadsheet importer example and the documentation within the block but have had no luck thus far, any help would be much appreciated.
Thank you,
Sam

Could you share the first few rows of the CSV file?

Sure, thanks for the response Mike.
Keep in mind that I’m using this csv as test. Appreciate the help.

Your script works for me! There’s something fishy about the output in your
original post: it includes a cell with the text “Sheet1”. A “sheet” is a
concept in a spreadsheet file (which normally has a filename like .xls
or
.ods
); CSV files don’t have sheets.
Usually, the file extension accurately describes the format of the data
inside, but sometimes things get mixed up. What makes this a bit tough to see
is that many popular spreadsheet applications quietly convert between the
formats to help you get your work done. So even though your seconds screenshot
shows that the file works in a spreadsheet application, it might not actually
be formatted in the way Airtable expects.
Are you able to verify that the file is indeed formatted with plain-test
comma-separated values? Or could you add the example file as an attachment
here?

I had the same thought, I’ve never seen a sheet number come up when uploading a CSV anywhere.
I don’t think file uploads are permitted through this site (I at least don’t see it, I could be missing it) but now that I know it’s not the script, I attempted the same script with other CSVs I had lying around and got the same result. Most of these CSVs have been converted from .xlsx or .xls file types.
It sounds like you’re right about something happening quietly that ends up in a format that Airtable doesn’t expect.
I’m not sure if this is particularly helpful but here’s a screenshot of the CSV text:
Do you have any advice for how I might be able to work around this issue? Do you need any additional information?
Thanks again.

Looks like the forum’s “upload” capabilities are limited to image files, so scratch that.
There are some small differences between the data in the second and third screenshots, but it doesn’t look like any of them are significant here.
We can take a look at the “raw” text contents using the HTML File API:
output.text(JSON.stringify(await csvFileResult.file.text()));
Does that report CSV-formatted text?

That seems to show us what we needed to see. Here is the output:
"statename,stateabr,Region,Region#\r\nAlabama,AL,Southeast,4\r\nAlaska,AK,West,1\r\nArizona,AZ,Southwest,2\r\nArkansas,AR,Southeast,4\r\nCalifornia,CA,West,1\r\nColorado,CO,West,1\r\nConnecticut,CT,Northeast,5\r\nDelaware,DE,Northeast,5\r\nFlorida,FL,Southeast,4\r\nGeorgia,GA,Southeast,4\r\nHawaii,HI,West,1\r\nIdaho,ID,West,1\r\nIllinois,IL,Midwest,3\r\nIndiana,IN,Midwest,3\r\nIowa,IA,Midwest,3\r\nKansas,KS,Midwest,3\r\nKentucky,KY,Southeast,4\r\nLouisiana,LA,Southeast,4\r\nMaine,ME,Northeast,5\r\nMaryland,MD,Northeast,5\r\nMassachusetts,MA,Northeast,5\r\nMichigan,MI,Midwest,3\r\nMinnesota,MN,Midwest,3\r\nMississippi,MS,Southeast,4\r\nMissouri,MO,Midwest,3\r\nMontana,MT,West,1\r\nNebraska,NE,Midwest,3\r\nNevada,NV,West,1\r\nNew Hampshire,NH,Northeast,5\r\nNew Jersey,NJ,Northeast,5\r\nNew Mexico,NM,Southwest,2\r\nNew York,NY,Northeast,5\r\nNorth Carolina,NC,Southeast,4…
Didn’t feel the need to put all the text in there. Definitely not just comma separated, looks like it’s returning to the start of a line then going to a new one. You have any advice on how to handle this? Thank you.

This is strange. The file apparently has Windows-style line endings, but I’ve
confirmed that works on my end, too.
Working backwards from your first screen shot, I have some guesses about the
structure of the parsedContents
object. It may be that if you access the
Sheet1
property, you’ll see the output you’re after:
But I wouldn’t recommend relying on that. We might be dealing with a platform
bug. Could you share your browser and operating system (I’m using Chromium on
Ubuntu 18.04). Also, I appreciate that you don’t want to fill this thread with
a lot of data, but there’s a chance that some content later on in the file is
triggering unexpected parser behavior. Could you shrink the file down to a size
that is small enough to share here (using the “raw” text method from my
previous reply) and that still renders incorrectly for you?

It seems like the block may be misinterpreting the file’s type on your system. Could you also share the result of:
output.text(csvFileResult.file.type);
(It’s "text/csv"
for me.)

I’m running Chrome on Windows 10.
Here’s the full raw text:

And the file type:
application/vnd.ms-excel
Well, that’s problematic I assume. Does this help clarify what’s wrong? I appreciate the quick responses, it’s incredibly helpful.
