How We Handle Client-Side CSV Merging Without Server Processing

1. 1Read CSV files using the FileReader API to access their contents
2. 2Parse CSV data using a library like Papa to handle quoted cells and escape characters
3. 3Merge parsed CSV data into a single array, handling mismatched columns by using a library like lodash to union column names
4. 4Use a library like FileSaver to save the merged CSV data as a new file
5. 5Test the merged CSV file for correctness, checking for proper column alignment and data integrity

Frontend developers and data analysts can benefit from this technique to efficiently merge CSV files in the browser, improving user experience and reducing server load
