So I tried to download a docx document as a report . by converting ajax response to a blob then an url ! the result is a document word that display a message , " we're sorry . we can't open because we found a problem with it's content .
there the main :
onDownloadReport: function (oEvent) {

var oAjaxBody = {

    SessionId: this.getModel("sessionModel").getData().SessionId,

    CustomerName: encodeURIComponent(this.getModel("sessionModel").getData().CustomerName.split("n")[0]),

    TenantInfo: encodeURIComponent(this.getModel("sessionModel").getData().TenantInfo)

        };

var sServiceUrl = "/SDC_XS_TEMP/APPL/SDC/services/serviceRuntime/xsjs/SDC_REPORT_GENERATE_MM.xsjs";



var me = this;

$.ajax({

    url: sServiceUrl,

    type: "POST",

    responseType:'arraybuffer',

    contentType: "application/json",

    data: JSON.stringify(oAjaxBody),

    // dataType: "json",

    success: function (oAjaxResponse) {

        var content = oAjaxResponse;

        var fileName = 'rapport.docx'; // You can use the .txt extension if you want

        me.downloadwithpost(fileName, content);

    },

    error: function (oError) {

        console.log("failure");

    }



});

and this is the function

downloadwithpost: function (filename, content) {

    var link = document.createElement('a');        

    var bytes = new Array(content.length);

    // var bytes = new Array(content.length);

    for (var i = 0; i < content.length; i++) {

        bytes[i] = content.charCodeAt(i);

    }

    var byteArray = new Uint8Array(bytes);

    var blob = new Blob([byteArray], {

        type: "application/vnd.openxmlformats-officedocument.wordprocessingml.document"                   

    });

    var url = URL.createObjectURL(blob);

    var oItem = {

        documentId: url,

        fileName: "rapport.docx",

        thumbnailUrl: "",

        url: url,

        selected: true

    };

    var oUploadCollection = this.getView().byId("uploadCollection");

    var newItem = new sap.m.UploadCollectionItem(oItem);

    oUploadCollection.addItem(newItem);

    oUploadCollection.downloadItem(newItem, true);

}

Take a look at this example, I worked with an hexadecimal data format, but you can change it as you see fit. Let me know if you need any help with this example or have any questions.

   doAfterSuccess: function(result, fileName, fileType) {       

            var filedata = result.ARRAY[0].FILEDATA; // get data from response

            // ------------------------------- hex data, rapport, docx

            var createdFile = this.createFile(filedata, fileName, fileType); 

            this.downloadFile(createdFile, fileName, fileType);

    },



    createFile: function(hexContent, filename, type) {

        var data = this.convertHexToBinary(hexContent); // skip if your data is not hex

        var file = new Blob([data], {

            name: filename,

            type: type

        });

        return file;

    },



    convertHexToBinary: function(hexContent) {

        return new Uint8Array(hexContent.match(/.{2}/g).map(function(e) 

        {

            return parseInt(e, 16);

        }));

    },

    downloadFile: function(file, filename, type){

        if (window.navigator.msSaveOrOpenBlob)

            window.navigator.msSaveOrOpenBlob(file, filename);

        else { // Others

            var a = document.createElement("a"),

                url = URL.createObjectURL(file);

            a.href = url;

            a.download = filename + "." + type;

            document.body.appendChild(a);

            a.click();

            setTimeout(function() {

                document.body.removeChild(a);

                window.URL.revokeObjectURL(url);

            }, 0);

        }

    },

function downloadDoc(filename, sServiceUrl, oAjaxBody){

    var xhr = new XMLHttpRequest();

    xhr.open('POST', sServiceUrl, true);

    xhr.responseType = 'blob';

    xhr.send(JSON.stringify(oAjaxBody));   

    xhr.onreadystatechange = function(){

        if (xhr.readyState == 4){

            //$.unblockUI();

            if(xhr.status == 200) {

                var blob = new Blob([xhr.response], { type: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document' });

                if (navigator.msSaveOrOpenBlob)

                    navigator.msSaveOrOpenBlob(blob, filename);

                else {

                    var link = document.createElement('a');                     

                    var URL = window.URL || window.webkitURL;

                    var downloadUrl = URL.createObjectURL(blob);

                    link.href = downloadUrl;

                    link.style = "display: none";

                    link.download = filename;

                    document.body.appendChild(link);

                    link.click();

                    setTimeout(function(){

                        document.body.removeChild(link);

                        window.URL.revokeObjectURL(downloadUrl);  

                    }, 100);

                }

            }

            else {

                console.log("failure");

            }

        }            

    }
