CSV Column Formatter

Upload a CSV and build a standardized export by selecting source columns, renaming headers, and setting defaults. Includes a mapping summary output for auditing.

📁 Step 1: Upload CSV

Reorder, rename, and standardize your output columns into a consistent export layout.

🗂️

🧱 Step 2: Define Output Columns

Each row below becomes one output column. Choose a source column (or leave as None and use a default value).

Output Column Name
Source Column
Default Value
Tip: If your input has more than 12 columns, set the mapping roughly here first. We can extend this UI to pull real headers in the next iteration.
⚙️ Step 3: Options

Outputs include a formatted CSV plus a mapping summary file.
