To split multiple sheets in an excel to multiple csv files - excel

I have a single Excel containing many sheets as sheet1, sheet2, sheet3, etc. I need to split this Excel into individual CSVs, i.e.
sheet1--->file1.csv
sheet2-->file2.csv
sheet3-->file3.csv
and so
on...
I need to do this either using PERL or UNIX. I also want to know the record count from each of the individually generated CSVs.
Since I am a beginner in Unix, I spent much time in writing the code and it doesn't seem working.
Please give your suggestions. Thanks in advance.


I was facing the same issue, I guess this post (link) should help you.Batch split xls sheets to csv -
This contains a js code which you just have to put inside the folder where you have all the xls files.It will split the sheets into separate csv and name them following this syntax: {file_name}-{worksheet_name}.csv
Hope this helps.


You can either use the csvkit program:
in2csv --write-sheets "-" -f Masterfile.xlsx
which will generate as many files as they are sheets
Masterfile_0.csv Masterfile_1.csv ...
or you can also use the ssconvert tool from the Gnumeric project:
ssconvert -S Masterfile.xlsx split_file.csv
but the naming scheme is less convenient as each file have the sheet number prepended (they need to be renamed):
split_file.csv.0 split_file.csv.1

Parsing sheets of Excel file with Talend

I'm working on Talend and recently my goal was to parse each sheet of an Excel file to do some different things.
For example, nowadays I'm working on an excel file composed of 4 sheets and I want to replace some values by other values in both sheets. The output file would be the same excel file, composed of its 4 sheets with all the values, including those replaced.
I used tFileExcelWorkbook and tFileExcelSheetList to parse my Excel file, then tFlowIterate to create a global variable (name of sheet) and tReplace to make the search/replace.
But actually I'm stuck.. I really don't know How to make it to create the same excel file, with the same sheets by using that tReplace component.
Do you know what I could do to solve that problem, and more generally how to do to parse sheets of an Excel file ?
Thanks !

Julien,
Easier way to parse/process sheets in an Excel would be to use a tFileInputExcel and in the "Sheet list" define the sheet names/position that needs to be worked on.

writing csv to open as different tabs in Excel

Is there some way to write a csv file such that , when opened in MS Excel , it will open in different tabs in the workspace ?

The short answer is, NO.
For that matter, the long answer is NO too.

csv is a continuous run of lines of values separated by commas. each line doesn't even have to have the same number of values etc. there's no concept of workbooks or different "areas" in csv. Excel cannot be cajoled into opening a csv into multiple workbooks...well at least not without writing VBA to parse the csv file yourself.
the oxml or whatever they've ended up calling the xml file spec for office, allows workbooks and is still easy to deal with being text based. Do you have to use csv or can you switch (at least part way through) to xml?

Reformat Data from CSV file

i have data from a csv file. One Column contains Text like "0.2.11" which i need to reformat to "00.02.0011", the leading zeroes and the length of the dot seperated parts are crucial. These are no dates, just random Numbers. How can i reformat those?
Thanks.

I know that this is an insanely long formula, but I believe it will do what you're looking for:
=IF(LEN(IF(ISERR(FIND(".",A1)),A1,LEFT(A1,FIND(".",A1)-1)))=2,IF(ISERR(FIND(".",A1)),A1,LEFT(A1,FIND(".",A1)-1)),"0"&IF(ISERR(FIND(".",A1)),A1,LEFT(A1,FIND(".",A1)-1)))&"."&IF(RIGHT(MID(A1,FIND(".",A1)+1,2))<>".",MID(A1,FIND(".",A1)+1,2),"0"&LEFT(MID(A1,FIND(".",A1)+1,2),1))&"."&IF(LEN(RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))))=4,RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))),IF(LEN(RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))))=3,"0"&RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))),IF(LEN(RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))))=2,"00"&RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))),"000"&RIGHT(A1,LEN(A1)-FIND("*",SUBSTITUTE(A1,".","*",LEN(A1)-LEN(SUBSTITUTE(A1,".",""))))))))
It's probably long enough that you'd have to save this in one of the new Excel formats like .xlsx or .xlsm for it to save. If you have trouble with it let me know, I also have the formula broken out into several cells (or steps) if you need it that way.

There is a shorter (but still ugly) Excel formula using TEXT function for formatting:
=TEXT(MID(A1,1,FIND(".",A1)-1),"00") &"."& TEXT(MID(A1,FIND(".",A1)+1,FIND(".",A1,FIND(".",A1)+1)-FIND(".",A1)-1),"00") &"."& TEXT(RIGHT(A1,LEN(A1)-FIND(".",A1,FIND(".",A1)+1)),"0000")
I would like to point out there are other methods of solving the same problem. If you have lots of big csv files you might consider preprocessing before importing into Excel. For example, doing the same job in awk is trivial:
BEGIN {
while(getline < "e.csv") {
split($1,a,".");
printf("%02d.%02d.%04d\n",a[1],a[2],a[3]);
}
}
Gawk works well with Windows. After installing, you can run it on the Windows or PowerShell command line as .\awk -f x.awk where x.awk is the above code in a text file.
