Cannot change file name in response

I’d like to provide a custom name for csv file, that is downloaded via Smart Action. Here’s my code:

const fileName = 'my_custom_filename';

res.set('Access-Control-Expose-Headers', 'Content-Disposition');
res.set('Content-Type', 'text/csv; charset=utf-8');

return res.send(exportData);

Expected behavior

I expect the downloaded file to have the custom name.

Actual behavior

File is called “collectionname.csv” (leads, to be exact) no matter how I try :slight_smile:


“express”: “~4.16.3”,
“forest-express”: “^7.5.0”,

Hi @Vasilii thank you to your feedback. Unfortunately it is not possible today. I push your request into our product board.

Hi, @Arnaud_Moncel

Turns out it’s possible :dart:

After a number of attempts, this code seems to be working just fine:

const fileName = 'custom_filename.csv';

    'Access-Control-Expose-Headers': 'Content-Disposition',
    'Content-Disposition': `attachment; filename="${fileName}"`,
    'Content-Type': 'text/csv; charset=utf-8'

return res.send(csvData);

Hi @Vasilii all right good news!
My bad for the bad response, we have different place who export is possible(eg: table view, has-many view) and the behavior is little bit different.
I’m happy to see you find the solution.
Thank you again.
