Insert a CSV Column

This lesson is part of Web Developer Tools · All levels

Summary

Insert a CSV Column adds a new column to a specific position on each row. New columns need header names and values for all records to keep the number of fields consistent. This operation is often used to add IDs, status, import dates, or categories before further data is processed.

Key points

Determine the name of the header and the position of the new column
The value content should be added to each line, not just the first line
Use a CSV parser to keep the commas and quotes in old data safe.
The default value must be consistent or follow the rule per line
Revalidate the number of fields after insertion
