Combine Multiple Files

Modified on Wed, 21 Jun 2023 at 08:23 PM


Gigasheet makes it easy to combine or merge many sheets into a singular sheet.  This is useful if you have consolidate smaller sets of data into one larger sheet. For example, you may have reports from the years 2019, 2020, 2021, and 2022. Gigasheet provides a tool where you can join all the files into a singular file for analysis.

To ensure your data matches, ensure the Column Headers are the same across two files.

You can rename column headers by Selecting the Header > Selecting Rename.

Each column will have a data type associated with it. Before combining sheets, you will want to ensure these data types match.
