How Do I Change Data in Multiple Excel Files?

Changing data in multiple Excel files can be a tedious task, but it's achievable with a few methods. Here's how you can do it:

1. Manual Method

Open each file individually: This is the most straightforward method, but it can be time-consuming for a large number of files.
Locate the data you want to change: Use the search function or navigate to the specific cells.
Make the changes: Enter the new data, edit existing data, or apply formulas.
Save the file: Repeat these steps for each file.

Open one file: This method allows you to apply changes to all files at once.
Go to the Find and Replace dialog box: This can be accessed by pressing Ctrl + H or through the Home tab > Editing group.
Enter the data you want to change in the "Find what" field: For example, if you want to replace "old data" with "new data," enter "old data" in this field.
Enter the new data in the "Replace with" field: Enter "new data" in this field.
Select "Replace All": This will apply the changes to all occurrences of the old data in the current file.
Repeat for other files: Open each file and repeat the Find and Replace process.

Record a macro: This method automates the process of changing data.
Select the data you want to change: This will be recorded in the macro.
Make the changes: This will also be recorded in the macro.
Stop recording the macro: The macro will now contain instructions for making the changes.
Run the macro on other files: This will apply the changes to all files.

Consider using dedicated software: There are several software tools designed to work with multiple Excel files.
These tools often offer features like: batch processing, data merging, and data transformation.

Import all files: This feature allows you to combine data from multiple files into a single table.
Apply transformations: You can then use Power Query's features to change the data as needed.
Export the data: The transformed data can then be exported to a new Excel file or another format.

Remember to back up your files before making any changes.
