# How to do a column sum when the cells are not numeric formatted

Hi, I want to do a column sum from an imported calc document about data usage. The data in the cells are like "1.38 MB", "870 Bytes", "25.6 KB" etc. Any help will be appreciated. Thanks for answers.

This is not a matter of the format set for the cells, but one of the recognition of text appended to the numeric part of the entries as a modifyier to the meaning.

To sum numeric data provided in text form is not a problem:
Assuming the range A2:A1001 {=SUM(IFERROR(VALUE(A2:A1001);"NotNumeric"))} entered for array-evaluation will do.

The factual task is therefor the implied one: How can I convert the the text parts looking like units with SI-like prefixes to numeric factors?

In your case you first should replace the wrongly used SI prefixes to the correct ones: M by Mi, K by Ki ...
How to do it is explained in detail in this attached example. I did not try to cobble a formula for a one-cell-solution. However splitting over so many helper columns may seem too detailed as soon as the solution is understood.

No Macro's just formula's! Will sum cells with # with or without a decimal and with or without text(s) at right of #'s. 1gb, 1g, 1 gb, 1.11gb etc. C:\fakepath\Sum Numbers having text at right.ods

Using regular expressions can be done with only one formula =SUMPRODUCT(VALUE(LEFT($O$7:$O$22;SEARCH("([^0-9\.\,]|$)";$O$7:$O$22;1)-1))), maybe your file was an excel file it has wildcards enable, not regular expressions, and formula is local seeting dependant..

( 2018-03-13 09:31:12 +0200 )edit Hi together, had just the same problem: Data from the ISP was in KB MB GB mixed up all together, like this 25 KB 311 KB 3,66 MB 34 KB 9,32 MB 3,03 MB 1,23 MB 3,47 MB 300 KB 49 KB 3,47 MB So before I can start here to count together, how much Bytes I daily spent on internet, I had to convert the whole row. I thought this problem must be a common and maybe already solved one, and yes I found that: https://www.mrexcel.com/board/threads/convert-mb-gb-kb-to-bytes.878293/ ...good man: =LEFT(A1,FIND(" ",A1))*1024^MATCH(RIGHT(A1,2),{"KB","MB","GB"},0) ...for M$Excel... So for Libre not directly usable: as in my case (for whatever reason I ever decided to use a german version of libreoffice...) I also had to figure out the right german names for the functions, but now I managed it and want to share it with you :-) :

25 KB   25600
311 KB  318464
3,66 MB 3837788,16
34 KB   34816
9,32 MB 9772728,32
3,03 MB 3177185,28
1,23 MB 1289748,48
3,47 MB 3638558,72
300 KB  307200
49 KB   50176
3,47 MB 3638558,72

TATA! :-)

...it souldn't be too hard to convert this into english... I am so happy after hours of work!

The hardest point was, that the character between last number and first letter ("K","M","G") was not a space...

but I haven't figured out which character it was: with the RECHTSB ("RIGHTB"?) function I got the last two characters for the VERGLEICH (MATCH) so I didn't investigate any longer ;-)

Enjoy, because we care and share!
