CSV File Splitter for Oversized Data Files

Why Big CSV Files Fail to Open

Excel stops at 1,048,576 rows per sheet (see Microsoft Excel specifications and limits). Cutting a file by hand in a text editor breaks rows. Corbett divides your file into clean parts below the limit in one pass.

Collected across 493 reviews from download portals and email support. Three reviews below are unedited.

20,000 contacts split

I had 20000 contacts in my CSV file which I couldn't open. When I use this tool, splitting my contact file into smaller chunks becomes easier and faster.

James

Shared with the team

I like the GUI of the software, because of how it is clean and straightforward. With the help of this tool, I split my big contact list and share it with my team without any difficulties. I like the preview options the most and perfect for managing the contacts.

Melissa

Data left unaltered

At first, I was a bit scared that this tool was legit and could break my CSV file without altering the data. But, after using it, all my issues are resolved. The fast, lightweight, and independent software is perfect for everyone.

Lauren

Before you split

Prepare Your CSV File for Splitting

Three short checks make your parts import cleanly.

Check the import limit

Look up the row or size limit of the CRM, mail tool or sheet that receives the parts. Set max rows per new file below it.

Repeat headers for imports

Most import tools map columns by header names. Select All files contain headers so every part imports on its own.

Keep UTF 8 for names

Accented and non Latin names stay in place in UTF 8. Save the source file that way before splitting.

Need CSV from other data first? Try Convert VCF to CSV or Export Outlook emails to CSV.

Good habits

How to Keep Your CSV Parts Clean

Good parts start with a careful job. Four habits keep your results tidy.

Copy your source file

Keep a spare copy of the CSV before you start so your original stays untouched.

Start with one folder

Split one small folder in free demo and open a part. Catch a wrong setting before a big job.

Check the part count

Compare the rows in your parts with the rows in your source file before you close the job.

Test one import

Import the first part into your target system before you load the rest.
