It is necessary to translate the lines into one line in bash, what is the best way?

Question

bash

Greetings gentlemen, there is a text:

[
  "test_tag1",
  "тэг_2",
  "тэг_3",
  "тэг_4"
]

You need to make a script that would eventually translate all lines with values ​​in " " into one line separated by commas. for example: test_tag1, tag_2, tag_3, tag_4 Tell me
in which direction to think at least) there was an idea to use the while read line loop to read lines with awk as a separator, use a regular expression that would take the text between quotes and then add it all into one line $ a, $a1, etc. Or maybe it's easier to do?

Answer 1

Maybe
x=`cat $my_file | grep -v "\[" | grep -v "\]" | sed s/\"//g | awk -vORS= '{print $1}'`

Answer 2
