pycharm如何對json文件格式化

1.json文件保存

將數據保存爲json格式，並存儲到.json文件中，需要注意鍵值對均用雙引號，而非單引號。
樣例如下所示：

{"sampleDB": {"shippedVsCustDemand": [{"CUSTOMER": "customer1", "ITEM": "desk", "SUPPLIEDQTY": 25, "DEMANDQTY": 3}, {"CUSTOMER": "customer1", "ITEM": "drawer", "SUPPLIEDQTY": 15, "DEMANDQTY": 12}, {"CUSTOMER": "customer1", "ITEM": "table", "SUPPLIEDQTY": 52, "DEMANDQTY": 6}, {"CUSTOMER": "customer2", "ITEM": "end table", "SUPPLIEDQTY": null, "DEMANDQTY": 5}, {"CUSTOMER": "customer2", "ITEM": "leg", "SUPPLIEDQTY": null, "DEMANDQTY": 10}, {"CUSTOMER": "customer2", "ITEM": "round table", "SUPPLIEDQTY": null, "DEMANDQTY": 15}, {"CUSTOMER": "customer3", "ITEM": "desk", "SUPPLIEDQTY": null, "DEMANDQTY": 21}, {"CUSTOMER": "customer3", "ITEM": "desk top", "SUPPLIEDQTY": null, "DEMANDQTY": 14}, {"CUSTOMER": "customer3", "ITEM": "end table", "SUPPLIEDQTY": 1, "DEMANDQTY": 7}], "totalManufItems": [{"ITEM": "desk", "TOTALMANUFQTY": 25}, {"ITEM": "end table", "TOTALMANUFQTY": 155}]}}

2.組合鍵

在pycharm中，使用組合鍵ctrl+alt+L進行格式化。
效果如下所示：
