How to save a report with the correct structure in a server

I have to save a report in a repository and generate an url link to the server, now y save the json file in my db and have the follow structure:

{"name": "Prueba reporte HSEQ", "type": "json", "report": {"slice": {"rows": [{"uniqueName": "f"}, {"uniqueName": "p"}], "columns": [{"uniqueName": "a"}, {"uniqueName": "q"}, {"uniqueName": "m"}, {"uniqueName": "[Measures]"}], "measures": [{"uniqueName": "dis", "aggregation": "sum"}, {"uniqueName": "hw", "aggregation": "sum"}, {"uniqueName": "cm", "aggregation": "sum"}, {"uniqueName": "mv", "aggregation": "max"}]}, "options": {"grid": {"showTotals": "off", "showGrandTotals": "off"}}, "version": "2.9.79", "conditions": [{"format": {"color": "#FFFFFF", "fontSize": "12px", "fontFamily": "Arial", "backgroundColor": "#DA3230"}, "formula": "#value > 80", "measure": "mv"}, {"format": {"color": "#FFFFFF", "fontSize": "12px", "fontFamily": "Arial", "backgroundColor": "#799E0F"}, "formula": "#value <= 80", "measure": "mv"}], "dataSource": {"type": "json", "mapping": {"a": {"caption": "Año"}, "d": {"caption": "Fecha y hora"}, "f": {"type": "string", "caption": "Flota"}, "m": {"caption": "Mes"}, "p": {"type": "string", "caption": "Placa"}, "q": {"caption": "Trimestre"}, "ac": {"type": "number", "caption": "Aceleraciones bruscas"}, "cm": {"type": "number", "caption": "Combustible consumido"}, "co": {"caption": "Conductor"}, "di": {"caption": "Dia"}, "ev": {"type": "number", "caption": "Excesos de velocidad"}, "fr": {"type": "number", "caption": "Frenadas bruscas"}, "gr": {"caption": "Grupo"}, "hw": {"type": "number", "caption": "Horas trabajadas"}, "id": {"type": "false"}, "mv": {"type": "number", "caption": "Máxima velocidad"}, "ra": {"type": "number", "caption": "Ralenti"}, "ri": {"type": "number", "caption": "Trayectos"}, "dis": {"type": "number", "caption": "Distancia"}, "idl": {"type": "number", "caption": "IDLE"}}, "filename": "https://web1.co/DOC/PivotTable/basic.json"}, "creationDate": "2024-06-20T13:41:21.138Z"}}

but this json don't fit the structure to load the report in the grid, I load a manual json on my server and call it from my bd, and works well, but this json have the structure of a archive when it save local, like this:

{
"dataSource": {
"type": "json",
"filename": "https://web1.co/DOC/PivotTable/basic.json",
"mapping": {
"f": {
"caption": "Flota",

}
},
"slice": {

{
"uniqueName": "p"
}
],
"columns": [
{

{

}
],
"measures": [
{
"uniqueName": "dis",
"aggregation": "sum"
},
{
"uniqueName": "hw",
"aggregation": "sum"
},
{
"uniqueName": "cm",
"aggregation": "sum"
},
{
"uniqueName": "mv",
"aggregation": "max"
}
]
},
"options": {
"grid": {
"showTotals": "off",
"showGrandTotals": "off"
}
},
"conditions": [
{
"formula": "#value > 80",
"measure": "mv",
"format": {
"backgroundColor": "#DA3230",
"color": "#FFFFFF",
"fontFamily": "Arial",
"fontSize": "12px"
}
},
{
"formula": "#value <= 80",
"measure": "mv",
"format": {
"backgroundColor": "#799E0F",
"color": "#FFFFFF",
"fontFamily": "Arial",
"fontSize": "12px"
}
}
],
"version": "2.9.79",
"creationDate": "2024-06-20T15:58:48.964Z"
}

Can you give me an example of how save in the server the data like this and not the other format?
