An analyst performing data cleansing wants to extract the first three digits of the value in the column for zip code. Which one spreadsheet function should the analyst use?

Rationale

The analyst should use the Left function to extract the first three digits of the zip code.

The Left function is specifically designed to return a specified number of characters from the beginning of a text string, making it ideal for extracting the first three digits of a zip code.

A (Right) YOUR ANSWER

The Right function retrieves a specified number of characters from the end of a text string. Using this function would be inappropriate for extracting the first three digits since it starts counting from the end, not the beginning, of the zip code.

B (Trim) YOUR ANSWER

The Trim function is used to remove extra spaces from text, particularly leading and trailing spaces. While it helps clean up text data for formatting purposes, it does not extract any characters from a string, making it unsuitable for the task of isolating the first three digits of a zip code.

C (Left) CORRECT

The Left function extracts a specified number of characters starting from the leftmost side of the string. For the zip code extraction task, using Left with the parameter set to 3 will yield exactly the first three digits, which is precisely what the analyst needs.

D (Lower) YOUR ANSWER

The Lower function converts all uppercase letters in a text string to lowercase. This function is not relevant for the extraction of digits from a zip code, as it does not manipulate the position or selection of characters in the string.

Conclusion

To extract the first three digits of a zip code, the Left function is the most suitable choice, as it directly addresses the requirement to take characters from the start of the string. The other functions—Right, Trim, and Lower—serve different purposes and do not achieve the goal of extracting specific digit sequences. Understanding the functionalities of these spreadsheet functions is crucial for effective data cleansing and manipulation tasks.
