This is part of the IFSC toolset released by Razorpay. You can find more details about the entire release at ifsc.razorpay.com.
If you are just looking for the dataset, go to the releases section and download the latest release.
The code is just the downloader portion that scrapes the entire dataset from the RBI. The list of Excel files can be found here. There is also a combined Excel file link around on the internet but that file doesn't seem to be updated.
You will need ruby and wget to run the script, which
is just sh bootstrap.sh. This will scrape the list page,
download all the excel files in the sheets/ directory,
parse them and generate datasets in the data/ directory.
The following files will be generated, with approx file sizes given as well:
| File | Size |
|---|---|
| IFSC.csv | 19M |
| IFSC.json | 40M |
| IFSC.marshal | 40M |
| IFSC.yml | 31M |
| IFSC-list.json | 1.8M |
| IFSC-list.marshal | 2.3M |
| IFSC-list.yml | 1.8M |
| IFSC-list.bloom | 246k |
The files with the -list suffix only contain the list of IFSC codes.
This can be used for validation purposes. The .bloom file is a binary
bloom filter dump generated and readable using the bloom-filter
ruby gem. It uses the bloom filter implementation from here.
Note that the bloom filter is always probabilistic, and will return false positives for at max 0.1% of the cases.
The data/by-bank directory holds multiple JSON files corresponding
to each bank, for faster lookups.
