Converting PDF documents to Excel spreadsheets is a vital need for developers working with data automation, reports, and analysis. Unlike static PDFs, Excel enables structured data manipulation and analysis. In this article, you’ll learn how to convert PDF to XLS or XLSX in C# .NET using the REST API, a powerful tool for high-fidelity PDF processing.

PDF to XLSX REST API

The Aspose.PDF Cloud SDK for .NET enables developers to efficiently extract data from PDFs and convert it into Excel format. Key features include:

  • Accurate Conversion: Retains table structures, layouts, and styles.
  • Support for XLS & XLSX: Flexibility to target the format you need.
  • Custom Output Options: Control worksheet structure, blank columns, and output path.
  • Cloud-Based: Works across platforms with no local installation needed.

Prerequisites

To begin:

  • Install the official SDK from NuGet:
Install-Package Aspose.PDF-Cloud

Create a free account at Aspose.Cloud dashboard to get your Client ID and Client Secret.

Prefer command-line tools? You can also use cURL with Aspose.PDF Cloud API.

Step 1: Generate Access Token:

curl -v "https://api.aspose.cloud/connect/token" \
 -X POST \
 -d "grant_type=client_credentials&client_id=YOUR_CLIENT_ID&client_secret=YOUR_CLIENT_SECRET" \
 -H "Content-Type: application/x-www-form-urlencoded" \
 -H "Accept: application/json"

Step 2: Convert PDF to XLSX:

curl -v "https://api.aspose.cloud/v3.0/pdf/{sourceFile}/convert/xlsx?insertBlankColumnAtFirst=false&minimizeTheNumberOfWorksheets=false&uniformWorksheets=true" \
-X GET \
-H "accept: multipart/form-data" \
-H "authorization: Bearer {YOUR_ACCESS_TOKEN}" \
-o "Conversion.xlsx"
  • Save resultant Excel directly to cloud storage:
curl -v "https://api.aspose.cloud/v3.0/pdf/{sourceFile}/convert/xlsx?outPath={myResultantFile}&insertBlankColumnAtFirst=false&minimizeTheNumberOfWorksheets=false&uniformWorksheets=true" \
-X PUT \
-H "accept: application/json" \
-H "authorization: Bearer {YOUR_ACCESS_TOKEN}" \
-d {}

Replace sourceFile with input PDF (available in the cloud storage), myResultantFile with converted Excel workbook and, YOUR_ACCESS_TOKEN with JWT access token generated above.
