用相同ID的值填充Excel中的空白单元格

Question

I'm not so advanced in excel I need help if is it possible to do. I have an excel with this column: ID - Value1 - Value2

I need to update the value1 (or value2): - only if are blank AND only if the row has the same ID

I make an example, I have this table:

    ID  Value1  Value2
A1  1   100 
A2  2       
A3  3       
A4  1            200
A5  2            250

Iwould like to fill all the empty cell in this way

    ID  Value1  Value2
A1  1   100      200
A2  2            250
A3  3       
A4  1   100      200
A5  2            250

Thank you for any help.

Ok, so your data is a mixture of numbers and texts. You can generate two new columns with the desired values using formulas. Choose two new, adjacent columns, say D and E, and enter this CSE formula in row say in cell D2 :

D2:
=IFERROR(IF(ISBLANK(B2),INDEX(B$2:B$99,
   MATCH(1,($A$2:$A$99=$A2)*(1-ISBLANK(B$2:B$99)),0)),B2), "")

Ctrl Shift Enter

Enter the formula in D2 with Ctrl Shift Enter and then copy/paste in the cells of columns D and E (or as I said any two adjacent columns).
