Splitting 1 item of binary files into 1 item per file

[c.le]

Hello,
I managed to decompress a zip file containing a dozen of files thanks to a Compression node. The output is only 1 item containing all the files as binary data.

I would like to extract text and filename from each file but I cannot loop on the output, as it is only 1 item !
I saw a closed question with a code node workaround to split 1 list of binary files into several items, but the script does not work any more.

Here is the closed question : Process decompressed files
Here is the old script given as an answer to this question:

let results = ;

for (item of items) {
for (key of Object.keys(item.binary)) {
results.push({
json: {
fileName: item.binary[key].fileName
},
binary: {
data: item.binary[key],
}
});
}
}

return results;

Thank you for your help!

Just an update to say that I finally copied the old Code component from the template to my workflow and it worked!

(I had not thought of this simple solution, as I am still not used to workf on n8n)

I am still wondering how to do the same thing in the new “Code” node, but for now I have a way to make my workflow run.

Hey @c.le hope all is good. Welcome to the community.
Just tried the code you posted above. Please see the result.

As you can see on the screenshot: 1 item coming in 2 items going out.

@c.le

but the script does not work any more.

Could you please clarify when you say “does not work”, what do you mean exactly? Could you show an example of this not working?

Hello @jabbson , I hope all is good for you too!
Thank you for looking into my issue: I realize now that I really need time to understand how to use n8n…
I actually did not try to use the code as I found it.

When I initially copied the code into my node, I saw an error under the “items” variable and altered the code immediately, before even trying.

As the error was “Cannot find name ‘items’. Did you mean ‘item’? “, I put “input.all()” instead of “items” and as it did not work (of course), I tried many other fruitless alterations…

The error message mislead me, sorry!

Glad to hear that the code worked. Sometimes the editor will show you error even if there are none, I don’t trust it .

You could have made this work with input.all() too.

let output = [];

for (const item of $input.all()) {
    for (key of Object.keys(item.binary)) {
        output.push({
            json: {
                fileName: item.binary[key].fileName
            },
            binary: {
                data: item.binary[key],
            }
        });
    }
}

return output;
