I'm struggling to download an Excel file in xlsx format in my Vue.js application. My Vue.js application make post request to the Node.js application which download that Excel file from remote SFTP server. Backend application works without any problems.
In Vue.js application I use next code:
axios.post(config.backendHost + '/excel', {
file_name: fileName
}).then((response) => {
const url = URL.createObjectURL(new Blob([response.data], {
type: 'application/vnd.ms-excel'
}))
const link = document.createElement('a')
link.href = url
link.setAttribute('download', fileName)
document.body.appendChild(link)
link.click()
});
After downloading file by browser, file opens automatically and I am experiencing an error that looks like this:
We found a problem with some content .xlsx. Do you want us to try and recover as much as we can?
You need to add the response type as a third argument in your post call
{
responseType: 'blob'
}
Your final code like that
axios.post(config.backendHost + '/excel', {
file_name: fileName
}, {
responseType: 'blob'
}).then((response) => {
const url = URL.createObjectURL(new Blob([response.data], {
type: 'application/vnd.ms-excel'
}))
const link = document.createElement('a')
link.href = url
link.setAttribute('download', fileName)
document.body.appendChild(link)
link.click()
});
Or you can use the library FileSaver.js to save your file
import FileSaver from 'file-saver'
axios.post(config.backendHost + '/excel', {
file_name: fileName
}, {
responseType: 'blob'
}).then((response) => {
// response.data is a blob type
FileSaver.saveAs(response.data, fileName);
});
my case worked:
axios.get(`/api/v1/companies/${companyId}/export`, {
responseType: 'blob',
}).then((response) => {
const url = URL.createObjectURL(new Blob([response.data]))
const link = document.createElement('a')
link.href = url
link.setAttribute(
'download',
`${companyId}-${new Date().toLocaleDateString()}.xlsx`
)
document.body.appendChild(link)
link.click()
})

I have downloaded a file through some options, using filesaver or [a]download, but only with the xlsx extension. When I try to download it as a .pdf, the file is downloaded, but it does get corrupted, and I am not able to view it, while the excel file is okay. The excel workbook is created using excel Js.
The piece of code that represents the problem is below.
private exportExcel(workbook: any, filename: string) {
workbook.xlsx.writeBuffer().then((data) => {
console.log(data);
let blob = new Blob([data], { type: 'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet' });
const anchor = document.createElement('a');
const url = URL.createObjectURL(blob);
anchor.href = url;
anchor.download = filename;
document.body.appendChild(anchor);
anchor.click();
document.body.removeChild(anchor);
URL.revokeObjectURL(url);
const urlpdf = URL.createObjectURL(new Blob([data], {type: "application/pdf"}));
fetch(urlpdf).then(res => res.blob()).then(blob => {
const data = URL.createObjectURL(blob);
const a = document.createElement('a');
a.href = data;
a.download = 'file';
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
URL.revokeObjectURL(data);
})
}).catch(err => console.log(err))
}
I have tryed it using fetch, not using blob (then I get an error) but none of the options exports a valid .pdf. Thanks in advance.
I am using angular framework
On the controller I return a path to where the excel file is located..Now I want to download that file
Below is my code:
reportExcel(val) {
axios
.get("/algn/api/report/" + val)
.then((res) => {
var url = res.data; // http://localhost.local/public/files/data.xlsx
const a = document.createElement("a");
a.href = url;
a.download = url.split("/").pop();
document.body.appendChild(a);
a.click();
document.body.removeChild(a);
})
.catch((error) => {
console.log(error);
});
},
I am getting the error as "Excel cannot open the file "data.xlsx" because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file". (The original excel file is still usable).
I have tried all the solutions which I found in google but nothing worked. Please help. Thanks
Try this:
reportExcel(val) {
axios
// add responseType
.get("/algn/api/report/" + val, {responseType : 'blob'})
.then((res) => {
const url = window.URL.createObjectURL(new Blob([res]));
const a = document.createElement("a");
a.href = url;
const filename = `file.xlsx`;
a.setAttribute('download', filename);
document.body.appendChild(link);
a.click();
a.remove();
})
.catch((error) => {
console.log(error);
});
},
Assuming the link gives correct excel file, we can inform that it is file (not the usual JSON) by specifying {responseType : 'blob'} in the request. Then, create the file using window.URL.createObjectURL(new Blob([res])). The rest is small adjustments to handle file instead of text.
Hello i download file using axios like so.
return axios({
method: "get",
url: URL,
responseType: "blob",
})
.then((response) => {
return {
...val,
blob: response.data,
};
})
.catch((_) => {
onError(val);
});
After that i store it in indexDB using Dexie.
const { id } = dataToSave;
return db.files.put(dataToSave, id);
I have file in db like blob
Next i want to save it like so:
download(myBlob, title, mimeType);
i try using filesaver,downloadjs or manualy
const { title, blob, mimeType } = material;
const url = window.URL.createObjectURL(blob);
const a = document.createElement("a");
a.style.display = "none";
a.href = url;
// the filename you want
a.download = title;
document.body.appendChild(a);
a.click();
setTimeout(() => {
window.URL.revokeObjectURL(url);
document.body.removeChild(a);
}, 1000);
It will download file only right after i download it to blob (browser session).
When i refresh page i get error WebkitBlobResource:1.
Any workaround of problem ? To either download file (pdf,html) or open it in new or same tab.
For now store data as arraybuffer, not blob works.
I am trying to download an excel file. I have used axios for it.
I have tried the below code
axios.post(backendURL + 'api/client?file_name='+file_name,params, {
file_name: file_name
}, {
responseType: 'blob'
}).then((response) => {
const url = URL.createObjectURL(new Blob([response.data], {
type: 'application/vnd.ms-excel'
}))
const link = document.createElement('a')
link.href = url
link.setAttribute('download', file_name)
document.body.appendChild(link)
link.click()
});
I am getting the error as "Excel cannot open the file "filename.xlsx" because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file"
