Json format

[Sina Dehghani]

Hello, I have a JSON file.. is there a way to understand values in the file? (I read all of the prives topics for this work but i can;t yhis work)

for example:

[HTML]{
"custom": {
"conditions": [
{
"id": "is-large-number",
"scriptName": "IsLargeNumber",
"highlight": true,
"params": [
{
"id": "number",
"type": "number"
}
]
}
],
"actions": [
{
"id": "do-alert",
"scriptName": "Alert",
"highlight": true
}
],
"expressions": [
{
"id": "double",
"expressionName": "Double",
"scriptName": "Double",
"highlight": true,
"returnType": "number",
"params": [
{
"id": "number",
"type": "number"
}
]
}
]
}
}[/HTML]


How can get value in this location:
"custom">>"expressions">>"params">>"id"
and update it to number1?


Thanks in advance
