HiLorenzo ,

#1 Analysis of the structure of records of say 3-5 IDs (between 2 '1980 Jan 12 wxyz LTE LL1 PDSCH Decoding Results')

[Anupam] Answered in 2
#2 For IDs where > 1 CRC values exist, do you report the 1st, the last, the min, the max..., all?

[Anupam] CRC supported values are only "0" or "1", and need to report all the CRCs( 0,1) for each of the records.

Algo should be like => Each Record has a Unique value of "Frame , SubFN",

So , From each record:-

We need :-

Frame, SubFN => from TB Top

CW Index => from TB Config

and CRC => from CB


#3 Manually or via formula do the job on say 3 different & representative IDs to allow checking the query output

[Anupam] Attaching a sheet(Sheet_3) doing manually for 3 records below:-

1980 Jan 12 04:29:31.203 [76] 0xB132 LTE LL1 PDSCH Decoding Results

1980 Jan 12 04:29:31.286 [BB] 0xB132 LTE LL1 PDSCH Decoding Results

1980 Jan 12 04:29:31.527 [1A] 0xB132 LTE LL1 PDSCH Decoding Results

 

Thanks in Advance,

Br,

Anupam

Hi anupambit1797 

 

Could you revise the title of this thread to help people who Search please?

i.e. 'Power Query/PowerBI Extract some values from complex CSV'

 

Re. #1 and #2 I was more looking at something like:

to help me work on #4. Done in attached file based on 3 different UIDs

 

To ensure we're on the same page, while I work on #4, could you please provide the expected result for '1980 Jan 12 04:29:42.758 [D8] 0xB132 LTE LL1 PDSCH Decoding Results' (table prepared in attached file, sheet 'Expected Result'?

      Hi anupambit1797 

       

      Attached is '1980 Jan 12 04:29:42.758 [D8] 0xB132 LTE LL1 PDSCH Decoding Results' from the CSV you initially shared

       

      In the Expected_Result you posted (I don't undersand why you did not use my file...) - just the first 2:

      Could you tell me where you find Frame = 828 and Frame = 832 in the attachment ???
