1. Sorting Records:

• Sorting records in a spreadsheet involves arranging data in a specified order based on one or more columns or criteria. This feature is essential for organizing and analyzing data effectively.

• Here's how it works:

  • Select the range of cells you want to sort.

  • Access the sorting feature, typically found in the "Data" or "Sort" menu.

  • Choose the column by which you want to sort the data, and specify whether it should be sorted in ascending or descending order.

  • Apply the sort, and the spreadsheet will rearrange the records accordingly.

Example: Suppose you have a spreadsheet with a list of names and corresponding scores. You can sort the records based on the "Scores" column in descending order to see the highest scorers at the top of the list.

2. Deactivating Automatic Changes:

• Deactivating automatic changes or automatic calculation is a feature that allows you to control when and how the spreadsheet recalculates values, such as formulas and functions.

• This can be useful in large spreadsheets with complex calculations, as automatic recalculations can slow down performance.

• To deactivate automatic changes:

  • Access the "Options" or "Preferences" menu in your spreadsheet software.

  • Look for settings related to automatic calculation or automatic updates.

  • Select "Manual" or a similar option to disable automatic changes.

  • You can manually trigger a recalculation when needed.

Example: In a financial model spreadsheet, you may want to deactivate automatic changes while you make several input adjustments to the model. Once all changes are made, you can manually recalculate the spreadsheet to see the updated results.

3. Validating Cell Content:

• Validating cell content ensures that data entered into cells meets specified criteria or constraints. This feature helps maintain data accuracy and consistency.

• Here's how to validate cell content:

  • Select the cell or cells you want to validate.

  • Access the data validation or content validation feature in the spreadsheet software.

  • Define the validation rules, such as acceptable value ranges, data types, or custom formulas.

  • Specify error messages or prompts that appear when invalid data is entered.

Example: In an inventory spreadsheet, you can set up data validation rules for the "Quantity" column. You might restrict input to positive whole numbers (no decimals or negative values) and display an error message if someone attempts to enter an invalid quantity.
