Hi, thanks for reaching out. The web-based CSV upload tool is a bit strict about correct formatting of the CSV file... Could you maybe post the first few rows from your file here? (or, even better, email the first rows as a CSV to us at firstname.lastname@example.org and we'll take a look).
If the CSV is formatted correctly though, the datalab command-line utility can be sometimes better suited for uploading to mydb. You can install it via:
pip install --ignore-installed --no-cache-dir noaodatalab
Then, log in once:
# enter username and password
and finally upload your CSV to mydb:
datalab mydb_import table='mytablename' data=./mytable.csv
And please be patient... After the upload seems to have completed (e.g., no more traffic in your network monitor), the prompt might still appear to be hanging; it is waiting for a response from the server, which will be sent once the table is really ready to use in mydb (for large tables this can take a while!).
Hoping that this is useful. Please let us know if we can assist further.
