Excel：在单元格中重新格式化/替换字符串的一部分

Question

I have an Excel file that contains descriptions:

Trees [1]
Buildings[20]
Cameras[303]

What I'm wanting to do is format what's inside the brackets to contain 4 digits. I know the custom format is "0000", but can I apply that format to those numbers?

The end result would look like:

Trees [0001]
Buildings[0020]
Cameras[0303]

Thank you for any tips!

Answer 1

假设Trees [1]位于A1单元上，然后尝试以下公式：

=LEFT(A1,FIND("[",A1))&RIGHT("0000"&MID(A1,FIND("[",A1)+1,LEN(A1)-FIND("[",A1)-1),4)&"]"

Answer 2

I'm going to assume that your number is always in [] , and those only occur once per string.

Using LEFT and MID to slice the string up, and then formatting the number, I end up with a formula that looks like this:

=LEFT(A1,FIND("[",A1)) & TEXT(VALUE(MID(A1,FIND("[",A1)+1,FIND("]",A1)-FIND("[",A1)-1)),"0000") & "]"

Broken down:

=LEFT(A1,FIND("[",A1)) << grab all the letters up to the [

& then add in:

TEXT(VALUE(MID(A1,FIND("[",A1)+1,FIND("]",A1)-FIND("[",A1)-1)),"0000") << the number ( VALUE ) found between the brackets ( FIND ), and then format that number ( TEXT ) to be the format you desire

& then add in:

"]" << the final close bracket
