I am currently working on an input file and I do have a column which contains 3 different values in one cell itself. Although this data is not being used in the transformation , I need to input this data from the source and then ignore when it is loaded into the staging table.
But the issue I face is that it gets loaded into separate rows rather than 1 cell.
This particular column is input as a string datatype. what change do I need to make to resolve this issue. Please let me know If more details are needed to answer the question.
I have uploaded a sample file to google drive https://drive.google.com/file/d/17hn8xmRd4CWsgKBzHgdwnR9W4jTJ9lTn/view?usp=sharing
The following is a screenshot of the csv data as opened in a text editor
Having downloaded sample.csv from your link, the first thing I did was open it in a text editor (Notepad++, TextPad, Visual Studio, etc) and just looked at what you have.
Row 1 is column headers
Encoded in UFT-8 with BOM (byte order marker)
Line Endings are CR/LF (Carriage Return & Line Feed)
Column delimiter appears to be a comma ,
Double Quote, ", is used as the text qualifier but only when needed
There are CR/LF characters in the actual data
I then define my flat file connection manager based on that data
Finally, I have a data flow with a Flat File Source to a Derived Column and drop a Data Viewer between them
As you can see, configuring your Flat File Connection Manager as I show will allow all the data to flow into your table as expected.
What is happening now is the CRLF, which is our row delimiter, is having precedence over the embedded CRLF in the column data. By setting the double quote as the Text Qualifier, the data reader correctly "skips" the embedded CRLF until it is encountered outside of the quotes.
I have some csv file which contains data like this 0234
When I open that csv, my libreoffice automatically converts value like 234 (leading zero removed)
libreoffice also formats some large numbers, so instead of original values i'm getting like: 13323+15
Question: can I somehow set-up libreoffice like so, that it never changed original values and opened file without any auto formatting ?
I have a txt file available on the web which contains tab separated values (TSV/CSV) like this:
Product_IdtabColortabPricetabQuantityItem1 tabRed tab$5.2 tab5Item2 tabBlue tab$7.5 tab10
I imported the txt file into a Google Spreadsheet using the IMPORTDATA(url) formula. The problem is that now I need to split the text to columns. I tried the following formulas without success:
Split(A1,"\t")
Split(A1," ")
Split(A1,"<tab>")
another thing I tried is to to use the Substitute function, but I just can't figure out how to match the Tab character in Google Spreadsheets?
Pages strips tabs by default when you paste text using a standard paste. Tab delimited data can be pasted and automatically parsed using:
Right Click -> Paste special -> Paste values only
IMPORTDATA(url) seems to handle tabs automatically, as others have mentioned before, if the URL ends in ".tsv".
I had trouble trying to import a file from Dropbox even though the file was named "something.tsv", because the url was
"https://www.dropbox.com/s/xxxxxxx/something.tsv?dl=1"
I managed to solve the problem by adding a dummy query parameter to the url:
"https://www.dropbox.com/s/xxxxxxx/something.tsv?dl=1&x=.tsv"
NOTE: I know this question was asked back in 2014 and I am answering this question some 5 years later. I am posting the answer here in hopes that someone else who googles their way here will be saved the headache and can be helped by how I devised a solution.
SUMMARY OF THE ISSUE: By default the IMPORTDATA() function will properly process a tab-delimited file only if the file name ends with the extension .TSV
UPDATE Nov 14, 2019:
In a comment below, Poul shared that he has found an undocumented parameter for the IMPORTDATA() function by which you can specify the delimiter to split the data. As of writing this, the official documentation makes no reference to this delimiter.
In effect the documentation should look something like the following:
IMPORTDATA("url","delimiter")
So, if you wanted to force a file to be split on the TAB character, it would look something like
IMPORTDATA("url","\t")
PRIOR ANSWER:
UPDATE: I am leaving my original answer just in case it might be helpful if the answer above, which includes undocumented functionality, does not continue to work.
ORIGINAL ANSWER: After seemingly countless attempts, I figured out how to coax Google Sheets into importing a tab-delimited file regardless of the extension.
For those looking for the quick and dirty answer, copy the following into a cell of a Google Sheet to give it a try:
=ARRAYFORMULA(IFERROR(SPLIT(IMPORTDATA("https://iso639-3.sil.org/sites/iso639-3/files/downloads/iso-639-3_Latin1.tab"),CHAR(9),FALSE,FALSE)))
For those that want to know a bit more, I will try to explain how each of the nested functions are helping to create the final solution:
=ARRAYFORMULA( IFERROR( SPLIT( IMPORTDATA(URL-HERE) ,CHAR(9),FALSE,FALSE) ) )
IMPORTDATA() - the primary function that pulls in the data file from the web
SPLIT - split the row by tab, note the use of char(09) to generate the tab character; also note the use of FALSE for the last parameter which was required in my case to ensure empty cells were not collapsed together
IFERROR - used to catch situations where an import might fail, the error will be trapped and not returned to the spreadsheet
ARRAYFORMULA - this function ensures that every line in the file is parsed; without this, only the first line of the file would be returned to the spreadsheet
It turns out that IMPORTDATA(url) can import a tab separated file, but it expects the file name to have the .tsv extension. This is inconsistent with Excel, where a tab-separated export results in *.txt.
If you can ensure that you use a .tsv extension, then your problem is solved.
You can also use the Sheets UI to import the file (into a new Spreadsheet). Select File > Import..., then Upload > Select a file from your computer. When the file selection dialog opens, paste the URL into the file name field, and click Open. The file will be downloaded to your PC then uploaded to Drive, through the Import dialog that will let you choose the delimiter.
(Validated on Windows 8.1 with Chrome; I don't know how this will behave on other OSes or browsers.)
Edit: See this gist.
importFromCSV(string fileName, string sheetName)
Populates a sheet with contents read from a CSV file located in the user's GDrive. If either parameter is not provided, the function will open inputBoxes to obtain them interactively.
Automatically detects tab or comma delimited input.
I had luck using split() and indicating only a single space as the delimiter, even though the data i pasted in had tabs separating each "column": =SPLIT(A1, " ", True) where A1 had data separated by 1 or more spaces. It seems that pasting in TSV data results in conversion from tabs to spaces.
This could be done in two steps leveraging the fact that tab is essentially multiple spaces.
Steps are as follows:
Select the columns which have tab separated data. Then trim tab to single space by using Data -> Data cleanup -> Trim whitespaces.
Now usual Data -> Split text to columns should work out of the box or after selecting space as separator.
Given a simple CSV file that consists of a string of digit characters and a date in UK format:
"00000000","01/01/2014"
and code to get the used cells:
IWorkbookSet workbookSet = SpreadsheetGear.Factory.GetWorkbookSet();
IWorkbook workbook = workbookSet.Workbooks.Open(#"C:\file.csv");
IRange cells = workbook.Worksheets[0].UsedRange;
when I access cells[0,0].Text it gives it as 0, because it's treating it as numeric and therefore the leading 0s are meaningless. It will do the same for the date. I'm trying to manually construct a DataTable from the cells, but I need the original values in the file.
I tried:
SpreadsheetGear.Advanced.Cells.IValues cells = (SpreadsheetGear.Advanced.Cells.IValues)workbook.Worksheets[0];
var sb = new StringBuilder();
cells[0,0].GetText(sb);
but nothing is appended to the string builder.
How can I get access to the original file values?
SpreadsheetGear does not make available the original values as found in in the CSV file (such as "00000000" in your case). You would only be able to access cell data after it has been parsed and processed by SpreadsheetGear (i.e., converting the above to a double value of 0). If you need the CSV's original values, then you'll need to open up file yourself and manually process and parse it.
It sounds like you ultimately want a DataTable, but if you still require to create a workbook file from your CSV data, once you've created a routine to manually open and parse each "cell" in your CSV file, you could enter each value into a spreadsheet as Text, so that it is preserved as it is found in the CSV file. You can go about this in two ways:
1) Set IRange.NumberFormat to "#", which will treat any future input into that IRange as Text. Example:
worksheet.Cells["A1"].NumberFormat = "#";
worksheet.Cells["A1"].Value = "00000000";
2) Prepend your inputted value with a single apostrophe, which indicates that you want the input to be treated as text. Example:
worksheet.Cells["A1"].Value = "'00000000";
If you still need a DataTable at this point, you could use the IRange.GetDataTable(...) method to accomplish this. Because the cell data is stored as Text, your DataTable values should also reflect these same values Example:
DataTable dt = worksheet.Cells["A1"].GetDataTable(GetDataFlags.None);
(There is a GetDataFlags.FormattedText option, but this isn't really relevant for your case since the cell data is stored as text anyway and so won't be formatted)
Is there any way i can trim the blank spaces when I read data from CSV file?
Thanks.
The SendMail task requires ';' between email ids. If you are building one large string to send your email to, consider using a script component to remove spaces and append a';' between each one.
Use a derived column component after the CSV input, in the editor you should see columns in top-left so drag the email column into the editor and replace any spaces with empty strings. You should also set the derived column to replace the email column (Or you could add it as a new column, if you need that).
