I started collecting car data in Excel voluntarily in 2003 and the hobby turned into business in 2012. My databases are now used by thousands businesses including car parts shops, tuning shops, car dealers, insurance, shipping services, etc. In the future I may offer API SaaS web service beside Excel download.
We all love music, but I may be the only person who made an Excel database and show to everyone what are my musical preferences in the style of a data scientist. Since 2005 I use Excel to organize the music I am listening, rate each songs from 0 to 16, then use complex mathematical formulas to calculate scores and rank best artists, best albums, best music genres, etc.
Database of private properties in Singapore: condos, apartments, executive condominiums, landed houses. Based on SingaporeExpats and PropertyGuru.
I offer data mining and web scraping services. “Scraping” usually means coding a bot that visit a list of given pages, copy specific data from each page and put it in an Excel / CSV file automatically, at rate of few pages per second. Watch the video!
If you are building a website, a mobile app, or just require specific data but cannot find in usable format, just give me link to a website having required data, I will make a scraper and turn website into an Excel database, for you and for future customers.
Excel, XLS, XLSX, CSV, SQL, XML, JSON
During my live I made over 100+ databases, from personal interest to distribute freely or sell for professional use. Some projects I made at request and published on website to allow other customers to purchase if interested. They have been used by numerous people from students practicing data analysis, to multi-national companies in real estate and automobile industry. I offer web scraping services in VB.NET and Python, making custom databases according your requirements. I work in Word and Excel, other file formats available: CSV, SQL, XML, JSON.
First time I made such table was in 2004 (15 years old) when I spent few days making in Paint an image with 48 hue levels and 32 lighting levels (Excel 97-2003 was limited to 56 colors).
In 2018 I remade it in Excel, adding RGB values for easier use, the job took about 4 hours, 48 hue levels and 16 lighting levels. In 2019 also made a Scalable Vector Graphics table with HEX colors.
Given by the success of Map of HDB blocks made for Singapore in September 2017, I started in January 2018 a similar project for Romania. By end-2022 the database contains over 32,000 buildings, being complete for Bucharest plus 7 of the 40 countries of Romania. In 2022 I bought a domain name dedicated to this project: www.hartablocuri.ro.
