Question

Remove headings and subtotals,

clean zeros and nonprintable characters,
format negative numbers,
correct inconsistencies across the data

Answer 1

Filter and sort to remove headings and subtotals, use find and replace to clean zeros and nonprintable characters, format negative numbers, and identify inconsistencies to correct them.

Step-by-step explanation:

In order to remove headings and subtotals from data, you can use the filtering or sorting feature in spreadsheet software such as Microsoft Excel. This allows you to exclude specific rows or columns that contain these additional information.

To clean zeros and nonprintable characters, you can use the find and replace function. For example, to remove all zeros, you can search for '0' and replace it with an empty string.

To format negative numbers, you can use the formatting options available in spreadsheet software. For instance, you can use parentheses or a negative sign to represent negative values.

To correct inconsistencies across the data, you need to identify the inconsistencies first. This could involve comparing data entries, identifying outliers, or applying specific rules to standardize the data.
