Specify encoding when loading documents

Introduction

GroupDocs.Viewer Cloud enables users to pass encoding when rendering text documents or email messages.

This feature is supported for:

  • Plain-text (.txt) files
  • Comma-separated values (.csv)
  • Tab-separated values (.tsv)
  • E-Mail Message (.eml)

Following code snippet sets the document encoding.

API Usage

There are steps that usage of GroupDocs.Viewer Cloud consists of:

  1. Upload input document into cloud storage
  2. Render document or get document info
  3. Download rendered document from storage

Steps 1 and 3 are storage operations, please refer to this File API documentation for usage details.

Swagger UI lets you call this REST API directly from the browser.
