Dynamically import table from excel sheet

Tue, 02 Feb 2016 07:35:03 GMT

Hi All,

I have an excel datasource in which data is coming in format, attached is the screenshot. I received this excel file on daily basis and want to pull data only from table containing table name "PQR". Since, the files are changing row number of that table is also changing.

So, how can I implement this in qlikview. Please help.

Thanks in Advance.

Hello,

'POR' should be a value of a new column for each table. So it's easy to read it with Qlikview.

Hope this helps!

Is this First time you are loading this excel file?

Please upload a sample of the spreadsheet. You can load this in Qlikview, but the details are a little complicated. The screenshot is not very useful and without a sample, you might not get any accurate answers.

I am attaching a sample file for your reference.

In the attached file I have three tables with table header (Transaction 1, Transaction 2, Transaction3...) and always I want to load data from transaction 2. How will I achieve this.

Hi,

Add this to script. Gave me what I think you looking for but as Jonathan pointed out, will need more detail if it does not as this can get a little complicated to dynamically account for

PQRRowsTABLE:

LOAD *, RowNo() as PQRRows

FROM

[directory\commdata.xlsx]

(ooxml, no labels, table is Sheet1);

PQRStartEnd:

LOAD PQRRows as PQRStartEnd

RESIDENT PQRRowsTABLE

WHERE A = 'PQR' or A = 'MNO';

LET zRowStart = Peek('PQRStartEnd',0)+2;

LET zRowEnd = Peek('PQRStartEnd',1);

PQRData:

LOAD

A as No,

B as Name,

C as Gender,

D as Address,

E as Phone

RESIDENT PQRRowsTABLE

WHERE PQRRows >= $(zRowStart) and PQRRows < $(zRowEnd) and (not isnull(A) or A='');

DROP TABLES PQRRowsTABLE, PQRStartEnd;

exit script;

Hi Vikas,

Thanks for sharing above line, but it doesn't work for me. In my case I have a file ,say Transaction 02-02-2016.xlsx. This files contain data divided in table format. Sample excel files has been attached above. I want to load data from single table "Transaction 2" and leave other tables untouched.

Hi,

Try something like below,

Temp:
LOAD
RecNo() as DataStart
From Format.xlsx
(ooxml, No Labels, Table is Sheet1)
WHERE A = 'Transaction2';

LET vHeaderSize = Peek('DataStart');
DROP TABLE Temp;

Data:
LOAD [Job ID]
  ,[Job Name]
  ,[Job Start Date]
  ,[Job End Date]
  ,[job status]
 From Format.xlsx
     (ooxml, embedded Labels, Header is $(vHeaderSize) Lines, Table is Sheet1)
     Where Not IsNull([Job Name]) and  [Job ID] <>'Job ID' ;

Sample QVW file attached against your file. Let me know

Close but this extends to transaction 3 which OP does not want, only transaction 2. Hence why I loaded a start and end

Byron,

I misunderstood question. I thought the OP wants to load data from second transaction. I guess the below one should work in that case.

Temp:

LOAD

RecNo() as DataStart

From Format.xlsx

(ooxml, No Labels, Table is Sheet1)

WHERE A = 'Transaction2';

LET vHeaderSize = Peek('DataStart');

DROP TABLE Temp;

Data:

LOAD [Job ID]

,[Job Name]

,[Job Start Date]

,[Job End Date]

,[job status]

From Format.xlsx

(ooxml, embedded Labels, Header is $(vHeaderSize) Lines, Table is Sheet1)

Where RecNo()= Autonumber([Job Name]);

I was trying to simplify the script.

That's really clever with the where clause, I like that!

Without knowing how the data is populated I wonder what would be the best approach. From a simplicity perspective, your solution requires less lines of code to get the desired result. In my solution, more lines are required but the constraint is not on any dimensional value so you always guaranteed to get just transaction 2, unless transaction 3 name changes. Likewise with the RecNo() approach, if Job Name happens to be named the same for any transaction then incorrect records would get fetched. So the two solutions both have constraints, one at a 'table name' level and the other at the field level.

I completely agree with you. But we don't have a choice for these kind of data. At first glance, I thought the same thing and was trying to find the first row and last row.
