How to pass component data to other components [duplicate]

I am developing a project in angular, in which I upload a file in json formats and show it in a table. Until now I have three components that are:

• UploadComponent
• TableComponent
• TableDetalleComponent

My question is how from UploadComponent I can send the data to TableComponent and TableDetalleComponent, this is my code:

import { Component, OnInit } from '@angular/core';
import { TableComponent } from '../table/table.component';
import { MatPaginator, MatSort, MatTableDataSource} from '@angular/material';
import {tableInf} from './upload.model';
import {UploadService} from '../services/upload.service';

@Component({
  selector: 'app-upload',
  templateUrl: './upload.component.html',
  styleUrls: ['./upload.component.css']
})



export class UploadComponent implements OnInit {

displayedColumns: string[] = ['noMaquina', 'cantidadDatos','promedioTCH', 'tiempoTrabajo', 'promedioVelocidad', 'noDescargas' ];
fileText;
datos;
datosServices;
nombre:any="";
mee=this;

fileUpload(event) {
   var reader = new FileReader();
   reader.readAsText(event.srcElement.files[0]);
   var me = this;
   reader.onload = function () {
     me.fileText = reader.result;
     var json = me.fileText;
     me.datos = JSON.parse(json)
     me.nombre=me.datos;
   }
   this.pruebas();
 }

 public pruebas(){
   alert("Mis datos: " + this.nombre.id);
   debugger;
 }


constructor() {}

  ngOnInit() {
  }
}

Please can you give me a help !!
