Dear KoboToolbox Support Team,

I’m encountering an issue with my form where the external CSV file (customer.csv) cannot be read despite being uploaded correctly. Here are the details:

Error Message

“Can’t find customer.csv” (appears when testing the form in Preview mode)

What I’ve Done to Fix It

  1. Verified the CSV is properly formatted (UTF-8, no BOM, correct columns).
  2. Created a ZIP file named customer.zip containing only customer.csv (no subfolders).
  3. Uploaded the ZIP to Settings → Media and confirmed the upload was successful.
  4. Cleared my browser cache and retested.

Attachments

  • My XLSForm
  • My CSV file
  • Screenshot of the Media page showing the uploaded ZIP: [Attac

Request

Could you please:

  1. Check if there’s a server-side issue preventing the file from being read?
  2. Confirm whether the ZIP was processed correctly?

Thank you for your assistance!

Welcome to the community, @modi! Cold you kindly let us know on why you zipped your CSV file? Is it too large?

My external CSV file has 84000 recorded customers so it is 1.38 MB (1,455,005 bytes) so it failed to be detected and i changed the approach by copying all the customer name combine with its meter number still so i had copy and paste the 84000 customer list and meter number and everything just stopped working
