Convert the Json data to Excel, Data is displayed in single row instead of multiple rows

Hi Team,
I am using the monday.com graphql api and getting the response as well. then converting from json to excel/csv format data is displayed in the single row instead of multiple rows.

eg . In the board having 5 columns with 10 rows. following query is used to get the json data, but converting from json to excel sheet all data is displayed in the single row.

Request query as follows,
query {
boards(ids:xyz){
columns{
title
}
items{
column_values{
text

  }
}

}
}
