VBA: Split data into Separate Workbooks

Thanks for the starting point! Was able to make a single file CSV split by column program after looking at your code. Thanks for posting this. Very useful. I wonder if it is easy to make each file have unique dates. For instance, I want 1st May of lines to be in one file only. I made it to split data by county, but it should work with any value you want to use as an identifier.

I am testing it now. I guess the column name has to be added instead of the "Unnamed". The code doesn't have a row or mb limit. The split by date will help. Hopefully, I can edit that and add a date range per month etc. Skip to content. Instantly share code, notes, and snippets. Code Revisions 8 Stars 96 Forks Embed What would you like to do?

For command-line manipulation of data, Unix really spoils us. Performing simple tasks like splitting a CSV file into several smaller ones is easy, thanks to thorough man pages and, most importantly, a large body of Stack Overflow questions that already cover nearly every use case.

So when I found myself on a Windows machine and having to split a several-thousand-line CSV file into several smaller files of just lines each for uploading to Google Keyword PlannerI was surprised by how difficult it was to find useful examples online. It's built in to every modern edition of Windows. To perform this simple task we need a basic loop and a couple of Cmdlets. Cmdlets are the Powershell equivalent of command-line programs on Unix.

We can use and chain them together in a similar way, piping output from one to the next, and so on. The pipe character behaves in the same way as on Unix, so we can read lines of the input file at a time and pipe them through to Out-File. The semicolon ends a statement, much like Bash:. A nice touch in Powershell is that we don't have to actually bother with traditional loop syntax.

The -ReadCount flag is smart enough to know that, if the output of Get-Content is piped somewhere, then -ReadCount lines should be sent through the pipeline each time. There's an assumption that you're going to be doing iterative things. So what we've created here is a pipeline, in which line chunks of the file are sent Now we just need to work out what to do with them. The function that consumes from this pipeline should write out the lines to a new, numbered, file.

And of course it should increment the value of iso that the next line chunk is written out to a new file. Here's how that looks in Powershell:. Of course, note that because we incremented i first, the output files will be numbered starting from the number 1. That's intentional here, but you could reverse the order of the statements in the code block above to start numbering from 0.We built Split CSV after we realized we kept having to split CSV files and could never remember what we used to do it last time and what the proper settings were.

We wanted no install, support for large files, the ability to know how far along we were in the split process, and easy notifications so we could get on with our other work rather than having to keep an eye on the process. We think we got it done! Sign In. CSV File bytes Preview. Header Rows.

Overview Review User Reviews Specs. Sometimes it's easier to split up a large file than to transfer or back up the whole thing. File Splitter is a free utility that does just that, as well as joining split files. It doesn't require installation, but in other respects we found it a bit inconvenient to use. Its main flaw is that it can't create self-joining file sets. The interface is clear, but it only provides built-in settings for splitting files onto floppy diskettes; many users will want to create files for burning to CDs, if not to DVDs.

File Splitter did show good speed in our tests, however, and if you don't mind figuring out the target file sizes yourself, it's an effective tool for cutting unwieldy files into manageable bits.
