Falsehoods Programmers Believe About CSVs
Much of my professional work for the last 10+ years has revolved around handing, importing and exporting CSV files. CSV files are frustratingly misunderstood, abused, and most of all underspecified. While RFC4180 exists, it is far from definitive and goes largely ignored.

Partially as a companion piece to my recent post about how CSV is an encoding nightmare, and partially an expression of frustration, I've decided to make a list of falsehoods programmers believe about CSVs. I recommend my previous post for a more in-depth coverage on the pains of CSVs encodings and how the default tooling (Excel) will ruin your day.

The problem of managing schemas
Good post on the pain of using CSV/JSON as a data interchange format:
eventually, the schema changes. Someone refactors the code generating the JSON and moves fields around, perhaps renaming few fields. The DBA added new columns to a MySQL table and this reflects in the CSVs dumped from the table. Now all those applications and scripts must be modified to handle both file formats. And since schema changes happen frequently, and often without warning, this results in both ugly and unmaintainable code, and in grumpy developers who are tired of having to modify their scripts again and again.
