File Upload Question

[Andrew_Learned]

Hey, I am stumped by what I expected to be a simple operation and looking for some help. I created a n8n form to simply upload a csv file. Then, attached that node to an extract from csv node expecting to be able to parse the csv rows. But I get “This operation expects the node’s input data to contain a binary file ‘file’, but none was found [item 0]”

I can’t seem to get the rows extracted when I upload the file in this way. Any suggestions?

Hi @Andrew_Learned,

Here’s how I do it. I bring it in as a read/write from disk. Then use a code block to parse it.

Best,

Robert

hello @Andrew_Learned, Welcome to n8n community

In your screenshot, I don’t see the binary file on the left, which explains the output error.

By the way, here’s a simple workflow for reference:

Oh, that’s simple too!

Though, I just realized my error. Basically, pinning the result of a form submission doesn’t keep the file-data stored. So, I needed to run it in real time, then pin the result to keep working on the flow…

Thanks for the assist though @rbreen!
