Use Nutrient DWS Processor API to convert Excel spreadsheets (XLS, XLSX) into PDF output without running Microsoft Office on your server. Start a free trial, test with Postman, and move to production with credit-based pricing.
Convert XLS and XLSX files to PDF while preserving tables, formatting, charts, and page layout — no Office license or local installation required.
Use REST, Postman, curl, JavaScript, Python, Java, C#, PHP, or HTTP to automate Excel-to-PDF conversion inside larger document processing pipelines.
Excel-to-PDF is one action in the DWS Processor API. Combine it with Word, PowerPoint, HTML, and image conversion in a single request.

The Excel-to-PDF API handles both legacy .xls and modern .xlsx spreadsheets through one endpoint, while the XLSX-to-PDF API is a dedicated endpoint for .xlsx only. Use Excel-to-PDF when your inputs include either format; use XLSX-to-PDF when you only ever send .xlsx.
No. Nutrient DWS Processor API converts spreadsheets to PDF server-side with no Microsoft Office license or installation required, so it runs in headless and containerized environments.
Both the legacy binary .xls format and the modern Office Open XML .xlsx format are supported. For exact version coverage, see the Processor API reference.
Tables, cell formatting, charts, and page layout are carried into the PDF output. Formula results are rendered as shown in the sheet rather than as live, recalculable formulas.
You can start free with Nutrient DWS credits and test with Postman before moving to credit-based Processor API pricing. For current per-request size and rate limits, see the Processor API reference and pricing.
