1. Please do not use line break in first row. You also can not use line break to custom field key.

2. Please quote all text columns. If you are using MS Excel, I recommend to switch to LibreOffice.

I can’t find why. Could you share your csv?

How “ignored” ? Could you share your csv again?

The gist is just an example. Please read comments in the code and fix to your custom fields. thanks

You can convert any column names with filter hooks. There is an example code on my blog post:

Could you try to post manually in your dashboard? You seems to try to import some multibyte characters, but some mysql settings do not allow to do that. I saw some similar posts in Japanese forum. Thanks

Please request support to your host like this problem. this support forum is only for csv importing issue. thanks
