将 json 文件转换为 linux jq 命令格式的 csv

Question

我想将 csv 中的 json 文件转换为我们想要的格式。 我只想从 json 中提取特定变量并将其格式化为 csv。

当前的 json 文件

我要提取并格式化为 csv 的字段是 “ID” “类型” “related_field_counts” “姓名” “描述”

如何使用 linux jq 命令提取这些？

Answer 1

要将这些字段提取到 csv，您可以在 shell 脚本中使用

jq

和

@csv

过滤器，如下所示：

#!/bin/bash


json=$(cat input.json)

fields=$(echo "$json" | jq -r '.[] | [
    .id,
    .type,
    .summary_fields.related_field_counts.inventories,
    .summary_fields.related_field_counts.teams,
    .summary_fields.related_field_counts.users,
    .summary_fields.related_field_counts.job_templates,
    .summary_fields.related_field_counts.admins,
    .summary_fields.related_field_counts.projects,
    .name,
    .description
] | @csv')


echo "id,type,inventories,teams,users,job_templates,admins,projects,name,description" > output.csv
echo "$fields" >> output.csv
