通過bash中的JQ命令將JSON轉換為CSV

Question

想要將json轉換為CSV文件。 CSV文件要求每行所有訂單項對象1 +該行還應包含PURCHASEORDERNO。

嘗試使用.HEADER []。PURCHASEORDERNO從LINE ARRAY訪問HEADER數組的對象PURCHASEORDERNO。 但是出現錯誤jq：錯誤（在：1）：無法遍歷null（空）

JQ命令：-

echo '{"RECEIPT":{"HEADER":[{"LINE":[{"ITEMCODE":"CF7219","QUANTITY":"6"},{"ITEMCODE":"CF7223","QUANTITY":"8"},{"ITEMCODE":"CF7223L","QUANTITY":"8"},{"ITEMCODE":"CF7419","QUANTITY":"6"},{"ITEMCODE":"CF7119","QUANTITY":"3"},{"ITEMCODE":"AP7119/7219L","QUANTITY":"4"},{"ITEMCODE":"CF7620","QUANTITY":"6"},{"ITEMCODE":"HP7313","QUANTITY":"40"}],"SUPPCUSTNAME":"CONFOIL CONTAINERS","SUPPCUSTCODE":"CON001","PROCESSDATE":"20190321","PURCHASEORDERNO":"P6254"},{"LINE":[{"ITEMCODE":"CF7219","QUANTITY":"6"},{"ITEMCODE":"CF7223","QUANTITY":"8"},{"ITEMCODE":"CF7223L","QUANTITY":"8"},{"ITEMCODE":"CF7419","QUANTITY":"6"},{"ITEMCODE":"CF7119","QUANTITY":"3"},{"ITEMCODE":"AP7119/7219L","QUANTITY":"4"},{"ITEMCODE":"CF7620","QUANTITY":"6"},{"ITEMCODE":"HP7313","QUANTITY":"40"}],"SUPPCUSTNAME":"CONFOIL CONTAINERS","SUPPCUSTCODE":"CON001","PROCESSDATE":"20190321","PURCHASEORDERNO":"P6254"}]}}'
 | jq -r '.RECEIPT.HEADER[].LINE[] | ["","ANCPACMEL","ADS",.HEADER[].PURCHASEORDERNO,"",.ITEMCODE,.QUANTITY,"","","","","","","","","","","","","","","","","","","","","","","","","","","",""]|@csv'

錯誤：-

Answer 1

您必須將PURCHASEORDERNO存儲在變量中，才能將其添加到每一行。

jq -r '.RECEIPT.HEADER[] | .PURCHASEORDERNO as $pono | .LINE[] | [ $pono, .ITEMCODE, .QUANTITY ] | @csv' input

用標題更新：

{
  echo '#Reference,ProductCode,Quantity'
  jq -r '.RECEIPT.HEADER[] | .PURCHASEORDERNO as $pono | .LINE[] | [ $pono, .ITEMCODE, .QUANTITY ] | @csv' input
} > output
