Converting an Excel document to PDF is simple. Customize conversion settings, like accessibility and archiving options, to suit your needs.

Convert Excel to PDF

To convert an Excel document to PDF, send a request to the /v1/conversion/excel-to-pdf endpoint, including both the Excel file as input and the settings JSON.

Curl

curl --location 'http://localhost:8003/v1/conversion/excel-to-pdf' \
--form 'file=@"ExpenseReport.xlsx"' \
--form 'settings="{
  \"File\": \"file\",
  \"Password\": null,
  \"PdfComplaince\": \"PDF/A-1B\"
}"'

JavaScript

const formdata = new FormData();
formdata.append("file", fileInput.files[0], "ExpenseReport.xlsx");
formdata.append("settings", "{\n  \"File\": \"file\",\n  \"Password\": null,\n  \"PdfComplaince\": \"PDF/A-1B\"\n}");

const requestOptions = {
  method: "POST",
  body: formdata,
  redirect: "follow"
};

fetch("http://localhost:4000/v1/conversion/excel-to-pdf", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

C#

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:8003/v1/conversion/excel-to-pdf");
var content = new MultipartFormDataContent();
content.Add(new StreamContent(File.OpenRead("ExpenseReport.xlsx")), "file", "ExpenseReport.xlsx");
content.Add(new StringContent("{
  \"File\": \"file\",
  \"Password\": null,
  \"PdfComplaince\": \"PDF/A-1B\"
}"), "settings");
request.Content = content;
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

Once the request is sent, it will create a conversion job to convert the Excel document to PDF and return the job details as follows:

{
    "jobID": "6be827c5-d86d-4fe5-9bd5-c8fd5887a455",
    "status": "requested",
    "createdAt": "2024-05-06T09:39:13.9505828Z"
}

Poll the status of the Conversion Job

Next, you can retrieve the job status by sending a request to the /v1/conversion/status/{jobID} endpoint with the job ID.

Curl

curl --location 'http://localhost:8003/v1/conversion/status/ef0766ab-bc74-456c-8143-782e730a89df' \

JavaScript

const requestOptions = {
  method: "GET",
  redirect: "follow"
};

fetch("http://localhost:4000/v1/conversion/status/4413bbb5-6b26-4c07-9af2-c26cd2c42fe3", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

C#

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:8003/v1/conversion/status/ef0766ab-bc74-456c-8143-782e730a89df");
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

You will receive one of the following statuses until the job is completed. Upon completion, you will receive the actual output file.

Job Statuses:

• Queued:

{
    "jobID": "4b2782b2-9f08-478b-98fc-4464bd219ca0",
    "status": "queued"
}

• In Progress:

{
    "jobID": "ef0766ab-bc74-456c-8143-782e730a89df",
    "status": "in progress"
}

• Error:

{
    "jobID": "ef0766ab-bc74-456c-8143-782e730a89df",
    "status": "errror",
    "code": "500",
    "message": "Failed to convert the document to PDF"        
}
