Sometimes Comma-Separated Values (CSV) files are exported with large numbers displayed in scientific notation. For this reason you may notice that exported tracking numbers appear truncated.
If your tracking numbers appear in scientific notation, it may cause uploading shipments via CSV import to fail. To fix this, please save your file then follow these steps:
- Go to the 'Data' menu > 'Import External Data' / 'Get External Data' > 'From Text' or rename the file extension to ".txt"
- Open the file, and you should see a dialog window appear
- Select 'Delimited file' and click through each window:
2nd window: Check (only) 'comma' under the delimiter column 
3rd window: Select each field and specify if you want the column to be read as text or number. Select 'Text' for large numbers.
Your tracking numbers should now be displayed in full. If not, there may be an error due to corruption in the file. You may need to repair your file and try these steps again.
