The basic steps for opening and editing a Word document

Open Microsoft Word, then go to File > Open and select your document from your computer. Once it loads, you can click anywhere in the text to place your cursor and start typing, deleting, or rewriting. To select a block of text, click at the start, hold down your mouse button, and drag to the end — then type to replace it or use the toolbar buttons to make it bold, italic, or underlined.

If you're working with a document someone sent you, it may open in Read-Only mode to prevent accidental changes. Look for a yellow banner at the top that says "Edit Document" or similar — click it to switch to editing mode. If you don't see that banner, go to File > Info and look for an Enable Editing button.

Save your changes by pressing Ctrl+S on Windows or Command+S on Mac. The first time you save, Word will ask where to store the file and what to name it. After that, the same keyboard shortcut saves over the existing file.

Key Takeaways

  • Click in the document to position your cursor, then type or delete text the same way you would in any text box.
  • Select text by clicking and dragging, then use the toolbar buttons or keyboard shortcuts to format it (bold, italic, underline, font size, color).
  • Documents sent to you may open in Read-Only mode — look for an "Edit Document" banner or check File > Info to enable editing.
  • Save your work with Ctrl+S (Windows) or Command+S (Mac) every few minutes to avoid losing changes.
  • Use Find & Replace (Ctrl+H or Command+H) to change the same word or phrase throughout the document at once.

Formatting text and paragraphs

The toolbar at the top of Word contains the most common formatting buttons. Highlight the text you want to change, then click Bold, Italic, or Underline. You can also change the font name, font size, or text color using the dropdown menus in that same toolbar. If you want to remove all formatting from a section of text, select it and press Ctrl+Spacebar on Windows or Command+Spacebar on Mac.

For paragraph-level changes, click anywhere in the paragraph you want to adjust, then use the alignment buttons to left-align, center, right-align, or justify the text. You can also increase or decrease the indent using the indent buttons, or add bullets and numbering from the toolbar. If you need more control, right-click the paragraph and select Paragraph to open a dialog with spacing, indentation, and line-height options.

Finding and replacing text

To search for a word or phrase, press Ctrl+F on Windows or Command+F on Mac. A search box will appear — type what you're looking for and Word will highlight every match in the document. Use the arrow buttons to jump between matches.

If you need to change a word throughout the document, press Ctrl+H on Windows or Command+H on Mac to open Find & Replace. Type the word you want to find in the first box and the replacement word in the second box. Click Replace All to change every instance at once, or click Replace one at a time if you want to review each change before it happens.

Adding and editing tables

To insert a table, go to the Insert tab at the top and click Table. A grid will appear — click and drag to select how many rows and columns you need, then click to create it. Word will place an empty table in your document.

Click inside any cell to type. Press Tab to move to the next cell to the right, or Shift+Tab to move left. To add a row at the bottom, click in the last cell and press Tab. To delete a row or column, right-click it and select Delete Rows or Delete Columns. You can also right-click a table to adjust its width, add shading to cells, or change the border style.

Working with images and objects

To insert an image, go to Insert > Pictures and choose whether to upload from your computer or search online. Select the image and click Insert. Once it's in the document, you can click and drag the corners to resize it, or right-click it to crop, rotate, or adjust the text wrapping (which controls whether text flows around the image or stays separate).

To add shapes, text boxes, or other objects, use the Insert tab. Click the type of object you want, then click and drag in your document to place it. You can format these objects by right-clicking them and selecting options like fill color, outline, or shadow.

Tracking changes and comments

If multiple people are editing the same document, you can turn on Track Changes to see who made what edits. Go to the Review tab and click Track Changes to turn it on. From that point forward, every deletion, insertion, and format change will be marked with a colored line and the editor's name. The original author can then review each change and click Accept or Reject.

To leave feedback without editing the document itself, use comments. Click where you want to add a comment, go to Review > New Comment, and type your note. The comment appears in a sidebar, and the other person can reply to it or delete it once they've addressed the issue.

Saving in different formats

By default, Word saves documents as .docx files, which is the standard format that works across Windows, Mac, and online. If you need to send the document to someone using an older version of Word, go to File > Save As and choose Word 97-2003 Document (.doc) from the dropdown.

You can also save as PDF, which locks the formatting and prevents accidental edits, or as a plain text file (.txt) if you only need the words without any formatting. Go to File > Save As, select the format you want from the Save as type dropdown, choose a location, and click Save.

Frequently Asked Questions

How do I undo a change I just made?

Press Ctrl+Z on Windows or Command+Z on Mac to undo your last action. You can press it multiple times to go back several steps. If you undo something by mistake, press Ctrl+Y or Command+Y to redo it.

Can I edit a Word document on my phone or tablet?

Yes. Microsoft Word has free apps for iPhone, iPad, and Android. read the app, sign in with a Microsoft account, and open your document. The editing tools are simplified compared to the desktop version, but you can still type, format text, and save changes. Documents sync automatically if you store them in OneDrive or SharePoint.

What's the difference between saving and exporting?

Saving keeps your document in Word format (.docx) and overwrites the previous version. Exporting converts it to a different format (PDF, plain text, etc.) and usually creates a new file without changing the original. Use Save for regular work and Export (or Save As) when you need a different file type.

How do I password-protect a Word document?

Go to File > Info > Protect Document and select Encrypt with Password. Type a password and click OK, then type it again to confirm. The next time someone opens the document, Word will ask for the password. Write it down somewhere safe — if you forget it, you cannot recover the document.
