Formating awk output to json using jq - bash

Question

I'm using grep to search for specific text inside multiple files.
grep -n -r "text_to_match" *
The output is:
john:15
Hana:11
After that, am using awk to print whatever meets my criteria of the condition
grep -n -r "text_to_match" * | awk -F '[:]' '{print $1,$2}'
I want now to use jq to have the following json document
{
"data": [
{
"name": "john",
"age": 15
},
{
"name": "Hana",
"age": 11
}
]
}
I tried the following:
jq -R 'split(" ") | { file:.[0], start_line:.[1]}'
Output
{
"name": "john",
"age": 15
}
{
"name": "Hana",
"age": 11
}
Thank you

As jq can also do the splitting, you could start before doing it with awk, having
john:15
Hana:11
Then, with -R you can read in the raw lines. Using -n in combination with [inputs] makes it an array. You can split using the / operator, and wrap everything in an object of your choice.
jq -Rn '{data: [inputs / ":" | {name: .[0], age: .[1]}]}'
{
"data": [
{
"name": "john",
"age": "15"
},
{
"name": "Hana",
"age": "11"
}
]
}
