Importing TimeStamp columns from excel to SQL DEVELOPER - excel

As it often happens there is a lot of questions similar to this one, but none of the ones I found gives me an answer to the issue I am having.
I am trying to import columns with Timestamp from Excel to SQL DEVELOPER. In the Picture 1 you can see formatting of the dates in excel. Format RRRR-MM-DD GG:MM:SS is Polish equivalent of English YYYY-MM-DD HH:MM:SS.
Picture 2 shows my NLS settings in SQL Developer and Picture 3 shows what i am getting while trying to transfer the data from excel. It looks like SQL somehow reads the format of the date on its own way? Or maybe excel stores the data in other way than its displayed while opening the workbook? Any ideas how to correct this?
Presentation of my data arrangements

As I figured out what was the issue and I think it might be useful information for other users I will present the solution.
What helped me, was formatting the timestamp in Excel column as a text. Meaning it could not be neither number formatted as timestamp, nor a result of TEXT FUNCTION. It had to be a plain text. In attached screen you can se what I tried to do and the results in SQL DEVELOPER.
To make values in C column I copied and pasted as values Column B - it pastes those as a text and not as a numbers.
Presentation of the solution
Hope this will help someone in the future.

Excel adds "1/1/1900" to my time duration entries and changes the time as it appears in formula box. Usual fixes not working

I have a column of time durations in an Excel sheet that is destroying my week. I wish I could make a custom hhh:mm format for this column, but I am only allowed to edit this sensitive document on SharePoint and Sharepoint does not support custom formats. Consequently, this is the best I can do for time duration:
Works fine. Most of the rows use this format. But inexplicably, many of the rows have this format instead:
This format difference messes with formulas, and as you can you see in the picture the time "duration" is different in the formula box. The time as it appears on the sheet is correct This format resists all attempts at change, and I've looked up quite a few solutions. Reformatting the whole column has no effect. Copy pasting the values in various ways either retains the problem or produces incorrect results. The Text to Columns fix I've read about in a few places gives me the time as it appears in the formula bar, not the (correct) time as it appears in the sheet.
I am extremely desperate for a fix. I appreciate whatever help you can provide. Please keep in mind that I cannot use custom formats on Sharepoint and I cannot edit this document elsewhere.

AnyLogic: False number format when exporting data to excel

I collect various data in time plots. If I copy the timeplot data and then paste it into Excel, the number format is often wrong. For example, I often get a date like Aug 94 instead of the actual number from the TimePlot. Unfortunately, I can't easily format this date into a number either, since the formatted number does not match the actual number from the timeplot. If I format the date in the same format as the number above and below, then I get the number 34547. However, this number does not correspond to the actual number of the TimePlot. Anyone know how I can prevent this problem?
You can only solve this on the Excel side, AnyLogic provides the raw data for you. Excel then interprets stuff. You can test it by pasting the chart raw data into a txt or csv file.
So either fix your Excel settings or paste into a csv, then into an xlsx.
Or better still: Do not manually paste at all. Instead, write your model results into the AnyLogic database and export to Excel from there: this takes away a lot of the pain for you. Check the example models to learn how to do that.
This is not AnyLogic question, rather an Excel & computer formatting problem. One way of resolving this is changing computer's date and time settings.
Another way is to save your output at txt file in AnyLogic. Replace all . with ,. Then open empty Excel, select Text format for the columns. Copy-paste from the txt file.
In Excel there are a few options
when you paste use paste as text only option
But this does not always work as Excel will still try to format the stuff for you
Use the Paste Special option and then choose text
Also possible this will not work, based on your Excel settings.
Paste using the text import wizard
(This works for me without fail)
On step 2 choose tab delimited
On step 3 choose Column format as text for every column (you need to select them in the little diagram below)
You will then see the data exactly as it came from AnyLogic. See the example below where I purposefully imported some text which has something that Excel will think is a date. You will now be able to see what in your data made Excel thing your data needed to be formatted the way it is and then you can fix it. (post a new question if you struggle with this conversion)
But as noted by other answers first prize is to write all the important data to external files. But I know that even I sometimes want to export data from a chart and review it in Excel. Option 3 works for me everytime

Why is the text in my excel spreadsheet created from csv treating everything as text?

I wrote a python script to generate some data into a csv file. The data looks something like the following:
12/10/2015 1 0:05:38 0:09:18 0:00:24 0:15:20
5/11/2016 1 0:39:07 3:22:09 0:00:08 4:01:24
7/27/2016 1 0:00:00 0:37:42 0:02:12 0:39:54
8/4/2016 1 0:00:00 0:00:29 0:00:35 0:01:04
10/3/2016 1 0:05:51 0:50:46 0:00:17 0:56:54
The data I am interested in analyzing is in the form of h:mm:ss but formuals that I write to sum the information doesn't work. I figured out that the ISTEXT(CELLNUM) is returning TRUE so it is clearly treating the data is text even if I manually reformat the cells as h:mm:ss. I must be overlooking something simple because there must be a way to do this easier without having to go through a process every time I open a CSV into excel and save it as a spreadsheet. How can I open this csv into excel and save as a spreadsheet in a way that I can setup formulas to sum the times? I might end up creating a lot of these CSV files so I need a way to do it that is fast. What am I missing? Why isn't simply selecting all of the cells and reformatting them working?
The best answer is posted here by jeeped
When you have pasted data from an external source (e.g. web pages are
horrific for this) into a worksheet and numbers, dates and/or times
come in as textual representations rather than true numbers, dates
and/or times usually the quickest method is to select the column and
choose Data ► Text to Columns ► Fixed Width ► Finish. This forces
Excel to reevaluate the text values and should revert the
pseudo-numbers into their true numerical values.
It's strange that excel can't figure this out or provide a way to do it as the data is imported. It can handle dates during import but not time. However the fact that I can so easily fix the time values one column at a time after saving as an xlsx file makes me wonder why Microsoft never bothered to just make it easier to specify what the columns are when bringing in the data the first time. Instead I have to search the internet for hours on end to ultimately find a solution that takes just a minute or two. Weird. There are some other answers posted for other types of data where you can use paste special to add a number to the existing data but those solutions do not seem to work for time.

Read excel cell colour into Power BI

I have an excel file that I need to read into Power BI. Unfortunately I have no control over this file as its auto generated from another person.
Some of the cells in this file are just filled with colours and I want to be able to translate these colours when importing the data into Power BI.
For example if the colour is green in excel then show true in the corresponding power BI cell. At the moment it's just blank.
Does anyone know of a way to get cell "meta" data like colour from excel in Power BI?
Don't give up just yet...
I found an example that works in a roundabout way using Power Query in Excel. It will give you the meta data associated with each cell by its address (e.g. A1 is highlighted with color FFFFFF00). I relied on some Excel functions to associate the highlighted cell addresses with the cell values. Pulling the cell data with Power BI might take some additional work.
The technique is to use Power Query to open the Excel .xlsx file, which is basically a .zip file containing .xml documents. The color information for each cell can be extracted into a table. From there I was able to use INDIRECT() statements to read from the .xlsx workbook and extract the values from the colored cells. It worked quite well for me.
You can find a working example in the forum in the link below. The user defined DecompressFiles function in the sample uses the Binary.Decompress command to access the XML files within the .xlsx file.
https://www.excelguru.ca/forums/showthread.php?7047-Extract-Cell-Color-with-M&p=28875&viewfull=1#post28875
In my situation, I had a database export of about 7,000 rows and 50 columns into Excel. Working offline, users then went through Excel and made changes, highlighting every cell they had changed. Then they wanted me to update the database with only the highlighted cells. The background color used by each person varied but I didn't care what the color was, just that it was colored.
For each changed cell I was able to generate SQL statements to update the database and also insert into a transaction log table. The main database table was mostly flat but the few foreign key lookup values that were modified I had to update manually.
Column F uses the Indirect formula to pull data from the source workbook. Note that the source workbook must be open for the Indirect formula to read from it.
=INDIRECT("'[" & Import_Filename & "]" & Sheet_Name & "'!"&[#[SheetCellRef.2]])
Column G refines the data in Column F by putting quotes around strings or NULL if the cell is blank.
Column H grabs the column heading to know what field to update.
Column K grabs the Record ID value from the row specified in Column E.
I have had to run this process three different times for the users so my time invested paid off quickly. All I have to do is put their latest highlighted Excel file in the local folder and refresh the Power Query to generate new SQL statements.
Sorry I don't have a 'solution' posted right here. The process is still a little fragile and I'm trying to make a more robust example I can share. Stack Overflow doesn't seem to be set up for ongoing development of a solution. The point of this answer is to give hope to some of you who are desperate for a solution and won't take 'No' for an answer.
Sigh.
Color is not data. Unfortunately, many people color-code cells and then expect to be able to do things based on the color of the cell. But it's not that simple.
Although Excel now provides some ways to filter by cell color, it still cannot identify cell color with a worksheet formula.
Hence, you will need a VBA routine that evaluates all cells and records their colors in another table, which you will then need to push into your Power BI data model.
In the long run, it might be easier to talk to that other person who produces the color coded cells, and teach them a better way of doing things. Show them how to use conditional formatting based on cell values for color coding. The logic used for conditional formatting can also be applied to classify the data in Power BI.
From a data architecture point of view, the best solution is to address the problem at the source, instead of creating tools to handle bad data input.
Just sayin'.

How to export SSIS to Microsoft Excel without additional software?

This question is long winded because I have been updating the question over a very long time trying to get SSIS to properly export Excel data. I managed to solve this issue, although not correctly. Aside from someone providing a correct answer, the solution listed in this question is not terrible.
The only answer I found was to create a single row named range wide enough for my columns. In the named range put sample data and hide it. SSIS appends the data and reads metadata from the single row (that is close enough for it to drop stuff in it). The data takes the format of the hidden single row. This allows headers, etc.
WOW what a pain in the butt. It will take over 450 days of exports to recover the time lost. However, I still love SSIS and will continue to use it because it is still way better than Filemaker LOL. My next attempt will be doing the same thing in the report server.
Original question notes:
If you are in Sql Server Integrations Services designer and want to export data to an Excel file starting on something other than the first line, lets say the forth line, how do you specify this?
I tried going in to the Excel Destination of the Data Flow, changed the AccessMode to OpenRowSet from Variable, then set the variable to "YPlatters$A4:I20000" This fails saying it cannot find the sheet. The sheet is called YPlatters.
I thought you could specify (Sheet$)(Starting Cell):(Ending Cell)?
Update
Apparently in Excel you can select a set of cells and name them with the name box. This allows you to select the name instead of the sheet without the $ dollar sign. Oddly enough, whatever the range you specify, it appends the data to the next row after the range. Oddly, as you add data, it increases the named selection's row count.
Another odd thing is the data takes the format of the last line of the range specified. My header rows are bold. If I specify a range that ends with the header row, the data appends to the row below, and makes all the entries bold. if you specify one row lower, it puts a blank line between the header row and the data, but the data is not bold.
Another update
No matter what I try, SSIS samples the "first row" of the file and sets the metadata according to what it finds. However, if you have sample data that has a value of zero but is formatted as the first row, it treats that column as text and inserts numeric values with a single quote in front ('123.34). I also tried headers that do not reflect the data types of the columns. I tried changing the metadata of the Excel destination, but it always changes it back when I run the project, then fails saying it will truncate data. If I tell it to ignore errors, it imports everything except that column.
Several days of several hours a piece later...
Another update
I tried every combination. A mostly working example is to create the named range starting with the column headers. Format your column headers as you want the data to look as the data takes on this format. In my example, these exist from A4 to E4, which is my defined range. SSIS appends to the row after the defined range, so defining A4 to E68 appends the rows starting at A69. You define the Connection as having the first row contains the field names. It takes on the metadata of the header row, oddly, not the second row, and it guesses at the data type, not the formatted data type of the column, i.e., headers are text, so all my metadata is text. If your headers are bold, so is all of your data.
I even tried making a sample data row without success... I don't think anyone actually uses Excel with the default MS SSIS export.
If you could define the "insert range" (A5 to E5) with no header row and format those columns (currency, not bold, etc.) without it skipping a row in Excel, this would be very helpful. From what I gather, noone uses SSIS to export Excel without a third party connection manager.
Any ideas on how to set this up properly so that data is formatted correctly, i.e., the metadata read from Excel is proper to the real data, and formatting inherits from the first row of data, not the headers in Excel?
One last update (July 17, 2009)
I got this to work very well. One thing I added to Excel was the IMEX=1 in the Excel connection string: "Excel 8.0;HDR=Yes;IMEX=1". This forces Excel (I think) to look at all rows to see what kind of data is in it. Generally, this does not drop information, say for instance if you have a zip code then about 9 rows down you have a zip+4, Excel without this blanks that field entirely without error. With IMEX=1, it recognizes that Zip is actually a character field instead of numeric.
And of course, one more update (August 27, 2009)
The IMEX=1 will succeed importing data with missing contents in the first 8 rows, but it will fail exporting data where no data exists. So, have it on your import connection string, but not your export Excel connection string.
I have to say, after so much fiddling, it works pretty well.
P.S. If you are using a x64 bit version, make sure you call the DTExec from C:\Program Files\Microsoft SQL Server\90\DTS.x86\Binn. It will load the 32 bit Excel driver and work fine.
Would it be easier to create the Excel Workbook in a script task, then just pick it up later in the flow?
The engine part of SSIS is good but the integration with Excel is awful
"Using SSIS in conjunction with Excel is like having hot tar funnelled up your iHole in a road cone"
Dr. Zim, I believe you were the one that originally brought up this question. I totally feel your pain. I love SSIS overall, but I absolutely hate the limited tools that come standard for Excel. All I want to do is Bold the Heading or Row1 record in Excel, and not bold the following records. I have not found a great way to do that; granted I am approaching this with no script tasks or custom extensions, but you would think something this simple would be a standard option. Looks like I may be forced to research and program up something fancy for a task that should be so fundamental. I've already spent a rediculous amount of time on this myself. Does anyone know if you can use Excel XML with Excel versions: 2000/XP/2003? Thanks.
This is an old thread but what about using a flat file connection and writing the data out as a formatted html document. Set the mime type in the page header to "application/excel". When you send the document as an attachment and the recipient opens the attachment, it will open a browser session but should pop Excel up over the top of it with the data formatted according to the style (CSS) specified in the page.
Can you have SSIS write the data to an Excel sheet starting at A1, then create another sheet, formatted as you like, that refers to the other sheet at A1, but displays it as A4? That is, on the "pretty" sheet, A4 would refer to A1 on the SSIS sheet.
This would allow SSIS to do what it's good for (manipulate table-based data), but allow the Excel to be formatted or manipulated however you'd like.
When excel is the destination in SSIS, or the target export type in SSRS, you do not have much control over formatting and specifying how you want the final file to be. I have written a custom excel rendering engine for SSRS once, as my client was so strict about the format of final Excel report generated. I used 'Excel xml' to get the job done inside my custom renderer. May be you can use XML output and convert it to Excel XML using XSLT.
I understand you would rather not use a script component so perhaps you could create your own custom task using the code that a script contains so that others can use this in the future. Check here for an example.
If this seems feasible the solution I used was CarlosAg Excel Xml Writer Library. With this you can create code which is similar to using the Interop library but produces excel in xml format. This avoids using the Interop object which can sometimes lead to excel processes hanging around.
Instead of using a roundabout way to do this exercise of trying to write data to particular cell(s), format the cell(s), style them which is indeed a very tedius effort considering the support SSIS has for EXCEL, we could go the "template" way to do this.
assume we need to write data in the so & so cell with all the custom formating thats done on it. Have all the formatting in a sheet, say "SheetActual", Whereas the cells that will hold the data will actually have Lookups/ refrences/ Formulaes to refer to the original data that SSIS exports in a hidden sheet say "SheetMasterHidden" of the same Excel connection. This "SheetMasterHidden" will essentially hold the master data in default format that SSIS writes data to the excel. This way you need not worry about formatting the data runtime.
Formatting the Excel is a one time work "IF" the formatting dont change very often. If the format changes and the format is decided runtime this solution maynot go very well.
The answer is in the question. Over time, it became a progress status. However, there is SSRS that will create Excel files if you create TABLE presentations. It works pretty well too.
