What tags exactly will not be imported?

Can you show us the first 3 or 4 lines of your file that you want to import?

and also please show the format string with which you import the data from the file

hi , i can't use mp3tag now
but i wanted to backup all the fields ,exported to cvs , all of them , but when i have imported i got some problems , i haven't even used format strings , just exported and imported

may i know an easy way to backup all the tags to a file?
so i will perform as soon as i can a test backup and import
thanks

This does not really make sense as the function to import needs a format string.
Please note that the sample export scripts are templates that you have to adapt according to your requirements.
And that means that you have to edit the export script to include the names of the fields that you have filled and remove references to properties that you don't need.
Also, you have to take into consideration whether the CSV format is the best for you as that might require some prior treatment of the field data so that the field contents does not collide with the format of "comma separated values" or the other requirement of 1 line per record. Esp. fields that may contain line breaks will cause problems in CSV files.

Why do you want to export all tags and re-import them at all?
Most of the content manipulations can be easily done inside Mp3tag without any external tools and without export and import.

If you let us know what you want to achieve, we can much better help you.

@LyricsLover
I know there is cut/copy and paste , i want just a backup ,save a back to a file ,that'sall

ps if i have edit it , i wanted to answer/reply to both

For a real backup, I highly suggest to backup your entire music files before you manipulate them in any way. This would also include all the covers for example. And all your songtext Lyrics.

As I said: the templates are just examples. Nobody can guess which fields you have in your files, so there is nothing ready-made.
As you already found the documentation about export scripts it should be easy to follow the links to the placeholders and scripting functions in this section:

The next step would be to find out which fields you want to export:
load all the files,
select all the files
Open the extended tags dialogue Alt-T
See the field names in the left column of that dialogue. If you want to export all tag fields from your files, you need to include all field names from the extended tags dialogue in the export script.

Again: take care of unprintable characters like line breaks, take care that the field separator in the export script cannot be found in the data of the referenced fields (e.g. a comma or semicolon).

Please note also, that a text file export does never include the embedded pictures.
