When clicking on the export button, some rows are empty in the exported CSV file.
Here is a sample content of the DataGrid:
Here is the exported CSV:
As you can see, all rows are exported in columns 2-5, but under the first column, only three are exported. The rest is empty.

The issue was on my side. For some reason, the URLs stored in firestore start with \n, and the data exported, but I could not see the value because of the control character.

I am using a GETPIVOTDATA function in Excel to source data from a pivot table generated by a Power BI query (everything was originally only in excel, the file got too large, so i stored the main tables in PBI but kept the reports in excel for mgmt's sake).
=GETPIVOTDATA("[Measures].["&$A$100&"]",'PIVOT Table_test'!$A$126,"[Master].[field1]","[Master].[field1].&["&C$26&"]","[Master].[AsofDate]","[Master].[AsofDate].&[2022-04-30T00:00:00]")
However, I want to make the GETPIVOTDATA function as dynamic as possible to prevent having too many hardcoded fields/items for each table that fields the charts we look at. However, when i reference the pivot table, the '[Asof]' field populates the static item as "...&[2022-04-30T00:00:00]")...
I have been trying to change that to reference a header row that contains a Short Date value (4/30/2022) like &["&$B&1"&"]")... but i keep getting #ref errors, every other field accepts the "&&" method, and when i leave the hardcoded timestamp in the formula, it populates.
So it has to be that reference but i do not understand what I am doing wrong. I have also tried changing the format of both the header row in Excel and the field within PBI but to no success.
Found the answer on another site. The solution in the item brackets is to write the following:
["&TEXT($A22,"yyyy-mm-dd""T00:00:00""")&"]
Anyone know how to add header to csv sink? I have a data flow that's source is a database table. Then I have used derived column and concatenated the columns to make one column and split the data in the column by commas (done in the source via a query). I have then selected the column that has been concatenated to be export to csv.
Data example:
Matt,Smith,10
Therefore I technically only have one column, however, I want to add a header for each section of the data.
Desired output:
FirstName,LastName,Age
Matt,Smith,10
You can add headers in CSV file.
Select Data Flow Activity.
Select Source and use Select activity.
Add column names as shown in below screenshot.
Finally add Sink and run Pipeline.
I am trying to create a data source in Tableau (10.0) where I am joining a table from SQL with an Excel file. The join happens on a site id but when reading the id from the excel source, Tableau strips the leading zeros (and SQL keeps leading zeros). I see this example
to add the leading zeros back as a new, calculated field. But the join is still dropping rows because the id is not properly formatted when making the join.
How do I get the excel data source to read the column with the leading zeros so I can do the join?
Launch Excel and choose to open a new blank workbook.
Click the Data tab and select From Text.
Browse to the saved CSV file and select Import.
Ensure that Delimited is selected and click Next.
Leave Tab as the delimiter and click Next.
Select the column containing the data with leading zeros and click
Text.
Repeat for each column which contains leading zeros.
Click Finish.
Click OK.
Never heard of or used tableau, but it sounds as though something (jet/ace database driver being used to read excel file?) is determining the column to be numeric and parsing the data as numbers, losing leading zeroes
If your attempts at putting them back are giving you grief, I'd recommend trying the other direction instead; get sqlserver to convert its strings to numbers. Number matching should be more reliable than String matching, so long as the two systems don't handle rounding differently :)
If your Excel file was read in from a CSV and the Site ID is showing "Number Stored as Text", I think you can solve your problem by telling Tableau on the Data Source entry that the field is actually a string. On the preview data source view, change the "#" (designating number) to string so that both the SQL source and the Excel source are both strings before doing the join.
This typically has to do with the way Excel stores values as mentioned above. I would play around with the number formatting for the Site ID column in Excel itself, not Tableau, and changed that two "Text" in Excel. You can verify if Tableau will read it properly with the leading 0s by exporting your excel file to csv and looking in the csv files to see if the leading 0s are still there.
How to export the entire query results to xls format without the value truncated (with the header intact).
e.g
the value is round up to 276408428673510000 when the actual value is suppose to be 276408428673508271
Using this method
After selecting the data by clicking 'Ctrl+ A' in gride, use 'Ctrl+Shift+C' to copy the data with Header. After pasting the data into MS Excel, try changing the 'format' to number or text. You must be knowing that 'format cells' is available as a right click option in MS Excel.
My solution was use the LPAD or RPAD functions, you give the exact length that you want and when you export the data, these don't round it.
I have 20 reports where the header and footer are not at all aligned. Because of that, while doing a CSV export, the file has lot of empty spaces. Is there an easy way to access the design part of the report programatically instead of changing the layout?.

If you do not want the template formatting to affect the CSV export, you shall use JRCsvMetadataExporter which extracts the data but not the formatting. So there won't be any empty spaces if the field has data. The order in which the columns should be printed in CSV can be fed programmatically.
Also to access the template design programmatically you can use JasperDesign object
