Ever wondered how to separate a huge dataset in Google Sheets into smaller groups the easy way? Split Sheet is your formula-free answer! There are only 3 SIMPLE SETTINGS: 

1. SELECT SHEET – SIZE DOESN'T MATTER
No matter how big your table is, the tool will divide your Google sheet without any formulas.

2a. DIVIDE GOOGLE SHEET BY KEY COLUMNS even without headers ;)
This add-on splits your Google sheet into multiple sheets based on the contents in the selected columns. The more key columns you choose to consider, the more precise and narrowed down your groups of data will be. A special option will let the tool process your summary table even if it doesn't have headers.

2b. SPLIT Google sheet BY N ROWS
Alternatively, you can split data by the number of rows you specify. Cut the table into equal-sized parts or set up several ranges of different amount of rows.

3. GET RESULT IN A CURRENT FILE / NEW FILE / MULTIPLE NEW SPREADSHEETS
Split Google sheet and place all outcome separate sheets to a current file or have the tool create a brand new spreadsheet and paste all sheets there.
