Hello Glide Community  
 ![image (1)](https://us1.discourse-cdn.com/flex002/uploads/glideapps/original/3X/6/e/6e08576b66b2dfaae1f39cc74f744050d4d0f093.png)  
,

I encountered an issue while trying to import a table into a new Big Table. During the process, an error occurred with the message:

“An unknown error occurred while importing the file. Error: 1001.”

I have attempted the process multiple times with the same result. I’ve followed all standard procedures for table import, and the file format appears to be correct. I would appreciate any guidance or troubleshooting steps to resolve this issue.

**Additional Information:**

- The error message appeared immediately after initiating the import.
- I was using a newly created Big Table in a fresh Glide project.
- I have attached a screenshot of the error message for reference.

Please let me know how I can resolve this and successfully import the table.

Thank you in advance for your help!

Best regards,  
Mike Schiessl

How big is your file? I think there might be an upper limit in terms of size.

The limit used to be 4.8MB, but I believe that’s been extended or removed.  
The warning is gone, and just recently I was able to successfully import a 17.2MB CSV file into a Big Table.

@mike_schiessl which format are you using?

I would suggest taking a small subset of your data and try importing into a regular Glide Table. This should help identify if the issue is specific to GBT.
