In this article, we'll show you how to show hidden rows in Google Sheets. Hiding rows and columns is as easy as showing them, but you need to know where the corresponding option / icon is.
Step 1. Open the Google Sheets site
Go to https://sheets.google.com in a web browser. If you are already signed in to your Google account, a list of your spreadsheets will be displayed.
If you haven't logged in to Google yet, do so now
Step 2. Open the table with hidden rows
If the row is hidden, you will see icons in the form of small triangles (above and below the hidden row) on the left gray panel with row numbers; also you will notice that the hidden line number is missing in the line number panel.
To hide a row, right-click on its number in the left panel of numbers and select "Hide row" from the menu
Step 3. Click the small triangle icon (▾) above or below the hidden row
This will show the hidden row again.
