If you are trying to upload a CSV or XLSX file and this is failing, please make sure you are uploading the correct format. For many exchanges, there are a number of different reports, and if you try importing the wrong report, the upload will fail.
Note: Make sure you are carefully following the instructions and that you are uploading the correct file.
You need to also make sure you do not open or change the file in any way before uploading. Sometimes your computer can change the format of the file, and this can cause the upload to fail.
If you have double-checked all of the above and the upload is still failing, then the exchange might have recently changed their format. Please contact support with:
