CSV Column Formatter
Reformat, reorder, and extract specific columns from CSV data.
The CSV Column Formatter extracts and reformats individual columns from CSV data. Select a column by number and output it as a list, or reformat it with different delimiters. Perfect for pulling a single column of data from a spreadsheet export without opening Excel.
What This Tool Does
When you only need one column from a CSV file - a list of emails, names, or IDs - opening a spreadsheet application is overkill. This tool lets you paste CSV data and extract any column by number. You can output the column as a vertical list, comma-separated values, or with a custom delimiter. It handles quoted fields correctly and supports different input delimiters. Quick, focused, and saves the overhead of opening heavy spreadsheet software.
Why Use This Tool
Sometimes you only need one piece of information from a spreadsheet - a list of emails, a column of IDs, or a set of names. Opening Excel or Google Sheets just to select and copy a column is slow, especially for large files. This tool extracts exactly the column you need in the format you need it. Whether you want a vertical list, a comma-separated string for a SQL query, or a custom-delimited format, you get the result in seconds without heavy software.
How to Use
- Paste your CSV data into the input box or upload a .csv file.
- Enter the column number you want to extract.
- Choose the output format - vertical list, comma-separated, or custom delimiter.
- Click Format Column and copy or download the result.
Common Use Cases
- Extracting an email column from a contacts CSV

Example
Tips
- Use column 1 numbering (not 0) - the first column is column 1
- If your CSV has headers, remember to skip the first row when you only want data values
- Output as comma-separated with quotes for direct use in SQL IN clauses
