How to Use This Tool

This tool adds a cumulative sum (running total) column to your CSV. Select a numeric column and the tool appends a new column showing the running total at each row.

  1. Provide your CSV — Paste CSV text into the input area, drop a CSV file onto the File tab, or enter a URL on the URL tab.
  2. Select a column — Choose the numeric column to compute the running total for.
  3. Get your output — Copy the result to your clipboard or save it as a .csv file.

FAQ

3 questions
Does this tool upload my data?
No. It runs entirely in your browser using JavaScript. Your CSV data is never sent to a server.
What is the new column named?
The new column is named after the source column with '_running_total' appended, e.g., 'salary_running_total'.
How are empty cells handled?
Empty cells in the source column are treated as zero for the running total calculation.
