Insert CSV Column

Adds a new column to an existing CSV dataset at a specified location. Users upload their comma-separated values file, select the desired insertion point, and then input data for the newly created column. The tool processes the spreadsheet structure, maintaining all original rows and columns while inserting placeholders or provided values in the chosen spot. It provides a functional way to restructure tabular data without needing specialized local software installations. Developers and data analysts utilize this utility when they must modify the schema of imported datasets programmatically but lack access to desktop editing tools. Professionals might use it to prepare raw log files, merge disparate data sources before database ingestion, or add calculated fields that were not originally present in the source file.
