Pro Tip – To decrease calculation times significantly on larger files that contain complex formulas, consider turning off automatic calculation by switching to manual mode while you do your work.

Copying and pasting formulae is like playing Russian roulette with your data, but with less vodka and more Excel.

Copying and Pasting Formulae

When working with Excel, the ability to copy and paste formulae is essential. Here’s a guide on how to do it effectively:

  1. Copying and Pasting Formulae: To copy a formula, select the cell with the formula, then press Ctrl+C or right-click and choose “Copy.” To paste the formula, select the destination cell and press Ctrl+V or right-click and choose “Paste.”
  2. Paste Special: For more control over what gets pasted, use “Paste Special.” This allows you to choose whether to paste just values or formats, as well as other options.
  3. Relative vs Absolute Referencing: When copying and pasting formulae, it’s important to understand relative vs absolute referencing. By default, cell references are relative, meaning that they change when copied to different cells. To make a reference absolute (so it doesn’t change), add a dollar sign ($) before the column letter and/or row number.
  4. Filling Down/Right: Another way to copy and paste formulae is by filling down (Ctrl+D) or filling right (Ctrl+R). This copies the formula from one cell to multiple cells in a sequence.

A helpful tip is to double-check that your formulas have copied over correctly before moving on with your work. Simply review your calculations after selecting ‘paste special’ for accuracy assurance!
