Count CSV Columns quickly analyzes your file and shows how many columns exist in each row. It’s perfect for catching broken rows, inconsistent structure, or malformed data in a spreadsheet. The summary updates live, works entirely in-browser, and highlights column counts line by line so you can spot problems immediately.

Example:

Input:

Name,Age,City  
Alice,30,New York
Bob,27
Charlie,33,Sydney

Output:

Line 1: 3 columns  
Line 2: 3 columns
Line 3: 2 columns
Line 4: 3 columns

Common Use Cases:

Use Count CSV Columns to validate the structure of a CSV before importing, find rows that are missing or have extra fields, or review exported files for consistency. It’s especially useful when working with large datasets, logs, or scraped text where column mismatches can cause issues downstream.

Useful Tools & Suggestions:

After counting columns, it’s smart to run Find CSV Dimensions to get the full picture of your file’s structure. And if something’s off, Trim CSV Columns can clean up trailing junk that might be throwing the count off.
