Pad order numbers to five digits with TEXT
Show a number with leading zeros so it matches the format another system expects.
TEXT
Formats a number as text using a format code, for padding, percentages and fixed decimals.
TEXT(value, format_text)
Text Functions.
=TEXT(42,"00000")
Returns 00042
Returns the number as text shaped by the format code: five digit positions, padded with zeros from the left.
The result is text. It will not sum, will not sort as a number and will not match a numeric lookup value, so pad for display or export and keep the real number in its own column.
Each of these is a wrong turn the practice exercises recognise and name. They are the misconceptions, not the answers.
Knowing what a function does and being able to write it from memory are different skills. These close the gap.
