Frequently Asked Questions
Do LEFT and RIGHT count spaces and punctuation as characters?
Yes. Excel counts every letter, number, space, and punctuation mark as one character. For example, if a cell begins with a space, that space is included among the characters returned by the LEFT function.
How can I ignore unwanted spaces before extracting characters?
Use the TRIM function around the cell reference. For example, =LEFT(TRIM(B6),4) removes leading and trailing spaces before returning the first four characters. TRIM also reduces multiple spaces between words to a single space.
What happens if N is greater than the number of characters in the cell?
LEFT and RIGHT return the entire text string. They do not add extra characters or return an error when N is greater than the length of the text.
Why does the formula return a #VALUE! error?
This error usually occurs when the number of characters is negative. Make sure the num_chars argument in the LEFT or RIGHT formula is zero or a positive number.
Do the extracted results update when the original text changes?
Results created with LEFT or RIGHT update automatically. When using Kutools for Excel, select the option to insert the results as formulas if you want them to update with the source text. Otherwise, Kutools returns fixed results.
