find on id and append value to json parameter - json

Question

I have the following data frame, df1:
A B C
123 B1 C1
456 B2 C2
And data frame df2:
A
[
{
"id": "123",
"details": {
"id": "123",
"color": null,
"param_1": {
"name": "mike"
},
"location": "US",
"items": [
{
"item_1": "#227858",
"offer_id": null,
"item_details": {
"detials_1": [{ "notes": "other:", "quantity": 1 }]
}
}
],
"version": 1,
}
}
]
[
{
"id": "456",
"details": {
"id": "456",
"color": null,
"param_1": {
"name": "james"
},
"location": "KR",
"items": [
{
"item_1": "#2221",
"offer_id": null,
"item_details": {
"detials_1": [{ "notes": "other", "quantity": 1 }]
}
}
],
"version": 2,
}
}
]
I want to find all values in df1[A] inside the JSON found inside df2[A] under the first instance of the id parameter. Once found, I want to replace the NULL values inside the color parameter with the df1[B] and offer_id with df1[C].
The output should create a new column with the appended values:
df2[B]:
[
{
"id": "123",
"details": {
"id": "123",
"color": B1,
"param_1": {
"name": "mike"
},
"location": "US",
"items": [
{
"item_1": "#227858",
"offer_id": C1,
"item_details": {
"detials_1": [{ "notes": "other:", "quantity": 1 }]
}
}
],
"version": 1,
}
}
]
[
{
"id": "456",
"details": {
"id": "456",
"color": B2,
"param_1": {
"name": "james"
},
"location": "KR",
"items": [
{
"item_1": "#2221",
"offer_id": C2,
"item_details": {
"detials_1": [{ "notes": "other", "quantity": 1 }]
}
}
],
"version": 2,
}
}
]
I just started researching how to approach this, but I need guidance on the most efficient way. Any insight would be greatly appreciated.
