Excel files store data and are useful. But what happens when you need to combine 10, 20, or even 100 files? Gigasheet makes it simple to merge files and analyze the full data set.
Upload individual CSV files, or zip files full of CSV files. Gigasheet makes it easy to select and combine hundreds of Excel files with the click of a button.
