Combine 3 CSVs and Download as Excel

This guide shows how to stack three monthly CSVs — january_sales.csv, february_sales.csv, and march_sales.csv — into one table and export the combined result as an Excel file.

Prerequisites

• Have an InstantRows project open
• Download the sample files:
  • January Sales (CSV)
  • February Sales (CSV)
  • March Sales (CSV)

Step 1 — Upload the CSVs

1. Go to the Home page and upload the january file
2. The web page should redirect to the view page where the data is present

Step 2 — Append February below January

1. Click upload
2. Select Source to append: february_sales.csv
3. The code will check if there is enough overlap in the columns
4. Choose Append
5. The data should refresh with the new rows and a step should be added

Step 3 — Append March to the result

1. Click the upload button again
2. Select Source: march_sales.csv
3. Apply Append
4. The data should refresh with the new rows and a step should be added

At this point, all three months are stacked into a single table.

Step 4 — Export to Excel (.xlsx)

1. Click Download → Excel (.xlsx) to download the combined file.

That’s it — you’ve combined three CSVs and created a single Excel download.
