Thank you for your help, yes i want only download it.I found this solution:

getExcelReport(data: myModel[]): void {
    const url: string = this.url  + '/MyController/GetExcelReport';
    this.Http.post(url, data, { responseType: 'blob' })
      .subscribe((response: Blob) => saveAs(response, `report.xlsx`));
  }

In API:

 [HttpPost] [Route("GetExcelReport")] public async Task<IActionResult> GetExcelReport([FromBody] IList<myModelType> myModel)

It worked for me
