How To Split CSV Into Multiple Files

Did you know that you can use Gigasheet to split a large CSV into multiple files in seconds?

Last week, I sat down with Gigasheet’s sales and customer success departments - as I wanted to identify the problems our customers face while working with huge data sets.

Whether you’re exporting data from a CRM, a database or external software, users are generating CSVs with millions of rows and thousands of columns. And the BIG problem is - spreadsheet software like Microsoft Excel or Google Sheets can’t load large CSVs:

One common task mentioned, was splitting a large CSV file into multiple files, for viewing in manageable pieces. (Worth noting, Gigasheet can also merge multiple CSVs online.)


Split CSV into Multiple Files

We have already established that splitting a large CSV file into multiple files using Microsoft Excel or Google Sheets is difficult because the file may simply be too big to open. But what if your CSV file size is small?


Even if it’s small, using Excel or Sheets to split a CSV into multiple files introduces a lot of opportunity for human error. To do so, you would copy and paste data from one file to another and use Save As to create multiple files. It would be very easy to duplicate a row, or accidently drop a row during the manual splitting process.


Don’t worry! We have some good news for you. What if I told you Gigasheet already allows its users to split a large CSV file into multiple files?
