Without having some example content, see what this Powershell code produces for you. Regards, Rob. Yes, Please provide a sample of the text uncorrected, and corrected In the basic sense, you can remove a comma and replace it with a space-bar character with an expression like this: Replace [txtAddress],","," ".

Thanks for the input. I tried it but didn't get meaningful output. Maybe I'm not using powershell properly. It seems it is trying to add a space after a comma? Assuming I make a ps1 file and add the above code, is the process to run it via a batch file?

I only want to process a line if there are too many commas. Anyone know how to get 'count of commas' in a sentence efficiently? I guess you really didn't care to get an answer to your other question, huh.

I already knew about the replace function but appreciate all input. Hi, with your test sample, I realise my code had some errors. I have corrected it, and it now works correctly, EXCEPT for the fact it seems to order the output columns alphabetically.

If you can verify that it works on your files, I'll work out a way to replicate the input order.Today's Posts. Quick Links. Search Forums. Show Threads. Show Posts. Shell Programming and Scripting.

How to remove commas from a CSV file (Extra commas in file) Need a vbscript / or powershell command

Hi I'm creating a sh script to generate a csv file. The CSV contains the values from a sql table. The content looks this: a,b,c,c2,c3,,,d,e I have some code that can separate the fields using the comma as delimiter, but some values actually contain commas, such asMy source system is sending.

We can remove the comma in between data fields by using shell script but can we handle this somehow in Abinitio!! Pls advise.

Paul but my dml is commadelimited and if comma is coming in between the data then all fields will be shifted and dml won't be able to read the file! Is that correct? Did you set the quote-character parameter? If so, please remove the definition and it will default to a quote. Thanks Paul. I will check that, i anyways don't wanted to remove the comma from the data because yaa its part of data!

Data is from unix box, will revert you back with the result. My File is a comma separated file but some fields may contain comma! In that case while reading the file wherever comma is detected, dml will consider it as a separate field and would not read the file properly.

I want to make my "," separated file as a pipe" " separated file and "," of the data should remain as it is. Input file: "niki, nick",24,"9, church hill", "niki, nick" 24 "9, church hill" Even in the solution that you suggested by using the escape quote character in the RSV component.

How does the ab initio parser actually detects the difference between the between fields and in the actual data I had a similar situation. I used read separated values component to read this kind of data. Please check the example given in the Ab Initio help under this component.

The csv module is useful for working with data exported from spreadsheets and databases into text files formatted with fields and records, commonly referred to as comma-separated value CSV format because commas are often used to separate the fields in a record.

The Python 2. Use reader to create a an object for reading data from a CSV file. The reader can be used as an iterator to process the rows of the file in order. For example:. The first argument to reader is the source of text lines. In this case, it is a file, but any iterable is accepted StringIO instances, lists, etc. Other optional arguments can be given to control how the input data is parsed.

This example file was exported from NeoOffice. Values with line breaks in the input retain the internal line breaks when returned by the parser.

How do I filter rows of a pandas DataFrame by column value?

Writing CSV files is just as easy as reading them. Use writer to create an object for writing, then iterate over the rows, using writerow to print them. The default quoting behavior is different for the writer, so the string column is not quoted. That is easy to change by adding a quoting argument to quote non-numeric values:. There is no well-defined standard for comma-separated value files, so the parser needs to be flexible.

This flexibility means there are many parameters to control how csv parses or writes data. Rather than passing each of these parameters to the reader and writer separately, they are grouped together conveniently into a dialect object. Dialect classes can be registered by name, so that callers of the csv module do not need to know the parameter settings in advance.

The standard library includes two dialects: exceland excel-tabs. The excel dialect is for working with data in the default export format for Microsoft Excel, and also works with OpenOffice or NeoOffice.

Suppose instead of using commas to delimit fields, the input file useslike this:. A dialect specifies all of the tokens used when parsing or writing a data file. Every aspect of the file format can be specified, from the way columns are delimited to the character used to escape a token.

The best way to configure a dialect for parsing an input file is to know the right settings in advance. For data where the dialect parameters are unknown, the Sniffer class can be used to make an educated guess.

The sniff method takes a sample of the input data and an optional argument giving the possible delimiter characters. In addition to working with sequences of data, the csv module includes classes for working with rows as dictionaries so that the fields can be named.

The DictReader and DictWriter classes translate rows to dictionaries instead of lists. Keys for the dictionary can be passed in, or inferred from the first row in the input when the row contains headers. The dictionary-based reader and writer are implemented as wrappers around the sequence-based classes, and use the same methods and arguments.

The only difference in the reader API is that rows are returned as dictionaries instead of lists or tuples. The DictWriter must be given a list of field names so it knows how to order the columns in the output.

I just upgraded to Windows 7 64 bit and installed a new license for Microsoft Office Enterprise, and now when I save the same file to CSV format, it adds commas for all the blank cells out to the last cell of the row with the most data.

Can someone tell me what is different or what I can do to make it ignore blank cells like it did before? I dont want the three commas after the second "yes" to be there. Here is a small macro that reads from one text file and writes to another.

Each record in the output file has trailing commas removed:. Did this solve your problem? Yes No. Sorry this didn't help. Thanks for the reply. I still dont understand what is different now though. Before it just worked without any additional steps? I feel like there is some setting that I am overlooking. Lots of programs won't care if there are extra trailing commas at the end.

For instance, excel won't care. It actually describes missing delimiter, but if some are "missing", maybe the ones appearing are "extra". But a lot of programs excel included don't care about those extra columns. Maybe you don't have to care, either??? Maybe you could write your own exporting program that would behave exactly the way you want:. Earl Kiosterud's Text Write program: www. Unfortunately for me the macro within Catia does not understand these new commas and errors out and aborts the creation of my tooling catalogue.

I need some help, I have a CSV file that contains an address field, whoever input the data into the original database used commas to separate different parts of the address - for example:. When I try to use the CSV file it treats this one entry as two separate fields when in fact it is a single field.

I have used Python to strip commas out where they are between inverted commas as it is easy to distinguish them from a comma that should actually be there, however this problem has me stumped. You can define the separating and quoting characters with Python's CSV reader. For example:. The CSV file was not generated properly. CSV files should have some form of escaping of text, usually using double-quotes:.

Either fix this manually or properly regenerate the CSV. Naturally, this cannot be fixed programatically. Edit: I just noticed something about "inverted commas" being used for escaping - if that is the case see Jason Sperske's answer, which is spot on.

Any help would be gratefully received. The problem is not how it is stored in the database but how the CSV file was generated. It will then have properly escaped string sequences.
