About the Author

My name is Andrii Protskiv. I work as software engineer since 2005. Full-time employee.

First my non-trivial pet project was ReportExporters library (2008) - set of .NET classes that allows .NET developers quickly (without rendering in code Open XML format file) export data into Excel file. In later 2000s JSON became more popular than XML file format. I thought it would be more easy to view JSON & XML content in spreadsheet (in various views and layouts). I started this web site 2014 with Json/Xml to Excel online conversion tool. In May 2021 with releasing JSON Online Editor this website became a SaaS. 

I want to say thank you to that few people who supported development by subscribing to monthly Subscription and RapidAPI plans, even if they use website tools rarely.

In 2022 I started HDCCS (Hashed Data & Criteria Comparison Service) project.

The first prototype of HDCCS API was released in 2023. 

Since HDCCS is a server technology there are 3 more projects to be implemented before HDCCS can become ready-made solution:

1. Questionnaire Editor (web or desktop app)
2. HDCCS Portal  - web app for companies who provide matching(matchmaking) services
3. HDCCS End-Client - web/desktop/mobile app for individuals
