Follow the steps given below to convert your first Word document or rich-text email into a PDF document using Google Docs & Spreadsheets.
Step 1: Assuming you already have a Google Account, upload your Word document to the Google Docs & Spreadsheets server here in one of the several ways provided.
Step 2: Open the uploaded document for editing. Usually this step is automated as the document automatically opens for editing immediately after upload.
