    Cell is blank but ISBLANK function says its not blank

    I have this file...........see enclosed........cell A1 looks blank........but the function ISBLANK in C1 indicates that the cell is NOT blank.

    Re: Cell is blank but ISBLANK function says its not blank

    The ISBLANK() function can be fooled by things under the hood like autofilter extract remnants and I'm sure many other things.

    You can test A1 this way to get a true answer:

    =A1=""

    Re: Cell is blank but ISBLANK function says its not blank

    That might be zero length null string., like when we use in formulas =""

    If you use this in C1,

    =A1=""

    will give you TRUE. If you want to convert select the range go to;

    Data >> Text to Columns

    Then click finish.

    Re: Cell is blank but ISBLANK function says its not blank

    the problem is when i use the countA function it "counts" this blank cell as NOT blank.

    not sure how to get around this.

    If the range contains only text not numbers (mixed alphabets & numbers OK), you can use this formula.

    =COUNTIF(A:A,"?*")

    If the range mixed with numbers & texts try this;

    =SUM(COUNTIF(A:A,{"?*","<9E300"}))

    Re: Cell is blank but ISBLANK function says its not blank

    when i use that formula in a defined name for plotting...........i am getting some really wierd results. i am enclosing a file for help explaining.

    WHen you open the file do the following:
    1) Change the named range "chrt_M_uat"
    From:
    OFFSET(Summary_UAT!$H$1,COUNTA(Summary_UAT!$H:$H)-1,0,-MIN(Summary_UAT!chrt_M_uat_len,COUNTA(Summary_UAT!$H:$H)-1),1)

    To:
    OFFSET(Summary_UAT!$H$1,SUM(COUNTIF(h:h,{"?*","<9E300"}))-1,0,-MIN(Summary_UAT!chrt_M_uat_len,SUM(COUNTIF(h:h,{"?*","<9E300"}))-1),1)


    2) Next try to update the graph as follows:
    click on one of the bars in the graph, then rt-click and goto select data. Then edit data for header1. Under teh series values change it from
    Summary_UAT!$I$2:$I$9
    to
    Summary_UAT!chrt_M_uat_A

    when you try to do this you get formula error. Now open up name manager and edit name "chrt_M_uat"...............its no longer the same? its somehow changed



    can anyone explain it?

    Re: Cell is blank but ISBLANK function says its not blank

    You have valid date in Col_H, just use COUNT instead of COUNTA, not necessary for COUNTIF(H:H,{"?*".....)

    Firstly define a name, Length

    =MAX(1,COUNT(Summary_UAT!$H:$H))

    Then change chrt_M_uat formula to;

    =OFFSET(Summary_UAT!$H$1,1,,MIN(chrt_M_uat_len,Length))

    Change $H$1 to $I$1, $J$1, $K$1, $L$1 for chrt_M_uat_A, B, C and D ranges.

    See the attached.

    Change Length formula to;

    =MAX(1,MIN(COUNT(Summary_UAT!$H:$H),chrt_M_uat_len))

    Then change chrt_M_uat formula to;

    =OFFSET(Summary_UAT!$H$1,1,,Length)
