how can i creat the directory of my blogs

[sigerio]

I need to learn different knowledge and categorize them into folders. I'd like to manage this content using a JSON-like format.There is an example what i want to achieve:
{
"linux": [
{
"name": "1"
},
{
"name": "2"
},
{
"name": "3"
}
],
"mcu": [
{
"name": "1"
},
{
"name": "2"
},
{
"name": "3"
}
],
"llm": [
{
"name": "1"
},
{
"name": "2"
},
{
"name": "3"
}
]
}
Thank u to much
