Challenge - 5 Problems

📊 Formula Result

intermediate

What is the output of this LABEL formula?

Given the formula =LABEL(A1:C1, {"Name", "Age", "City"}) in Google Sheets, what will be the output in the range A1:C1?

Google Sheets

=LABEL(A1:C1, {"Name", "Age", "City"})

A The cells A1, B1, and C1 will display "Name", "Age", and "City" respectively.

B The formula will clear the contents of A1:C1 without adding any labels.

C The formula will produce a #NAME? error because LABEL is not a valid function.

D The formula will display the array {"Name", "Age", "City"} as text in cell A1 only.

💡 Hint

Check if LABEL is a valid function in Google Sheets.

Google Sheets does not have a function named LABEL. Trying to use it will result in a #NAME? error.

🎯 Scenario

How to add headers to a data range without typing in cells?

You want to add column headers "Product", "Price", "Quantity" above your data in cells A2:C10 without manually typing them in A1:C1. Which formula approach can you use?

A Use <code>=SETHEADER(A1:C1, {"Product", "Price", "Quantity"})</code> in cell A1.

B Use <code>=ARRAYFORMULA({"Product", "Price", "Quantity"; A2:C10})</code> in cell A1.

C Use <code>=TRANSPOSE({"Product", "Price", "Quantity"})</code> in cell A1.

D Use <code>=LABEL(A1:C1, {"Product", "Price", "Quantity"})</code> in cell A1.

💡 Hint

Think about combining headers and data into one array.

The ARRAYFORMULA with curly braces and a semicolon stacks the header row above the data range dynamically.

❓ Function Choice

Which function can dynamically label columns based on the first row?

You want to create a dynamic named range that uses the first row as column headers for your data in A1:D100. Which function helps you extract the headers as a list?

A INDEX(A1:D1, 1, 0)

B FILTER(A2:D100, A1:D1)

C TRANSPOSE(A1:D1)

D SPLIT(A1:D1, ",")

💡 Hint

You want to get the entire first row as a horizontal array.

INDEX with row 1 and column 0 returns the entire first row as an array of headers.

How many columns will be labeled by this formula?

Given the formula =ARRAYFORMULA({"ID", "Name", "Score"; A2:C10}) in cell A1, how many columns will have headers labeled?

Google Sheets

=ARRAYFORMULA({"ID", "Name", "Score"; A2:C10})

A 3 columns will have headers labeled.

B Only 1 column will have a header labeled.

C No columns will have headers labeled because the formula is invalid.

D 4 columns will have headers labeled.

💡 Hint

Count the number of items in the header array.

The header array has 3 items, so 3 columns will be labeled.

What error occurs when using LABEL function in Google Sheets?

You enter =LABEL(A1:C1, {"A", "B", "C"}) in Google Sheets. What error message will you see?

Google Sheets

=LABEL(A1:C1, {"A", "B", "C"})

A No error; the labels are applied successfully.

B #REF! error because the range is invalid.

C #VALUE! error because the array is malformed.

D #NAME? error because LABEL is not a recognized function.

💡 Hint

Check if LABEL is a built-in function in Google Sheets.

LABEL is not a valid function in Google Sheets, so it returns a #NAME? error.
