CSV Parser in Go

I was working on a project where we had multiple services with in one project (e.g. Web, SafeKeeping, IOS, Call Notice, etc.). WEB was the front-end that will let the user upload the CSV file, and prepare it. After that, other services can collect the data using a POST request.

The whole CSV file parsing is devided into 2 parts...

• MultipartWriter()
• MultipartReader()

MultipartWriter

It converts the contents of the passed/received file into a multipart.Writer form file so the data can be passed to next service.

It returns the correct HTTP Content-Type, the form content as bytes, and a possible error.

(WEB service will collect the CSV file from the user, prepare it using MultipartWriter() and send it off to other/next service.)

MultipartReader

It reads the records from the passed/received CSV-encoded file and returns the parsed data (in a 2D String slice format) to the next service.

It also gives an option to include or exclude file header.

(Other services will collect the file/data from the POST request and parse it using the MultipartReader())
