## About IdeaFast

IdeaFast (ideafast.pro) checks the problem behind a startup idea against Reddit: it finds what people keep complaining about, scores each problem 0 to 100 and links every one to its threads.

Pick the subreddits where your customers talk, and a scan groups their posts into recurring problems with real quotes, so you read what people wrote in their own words, not a summary. You can also paste a written idea and get an evidence report with a verdict, or turn a problem into startup ideas.

Pay once, no subscription. Scans never expire, and your first scan is free with no card. A free library of scored problems needs no account: https://www.ideafast.pro/explore

Made for founders and indie builders before they build: testing one idea, or choosing what to build in a niche.

## About JSON to CSV Converter

JSON to CSV Converter is a free web tool that turns JSON data into CSV files. You can paste raw JSON, upload a .json file, or fetch a public JSON endpoint by URL. The conversion runs in your browser, so the data is parsed and converted locally without being uploaded to a server.

The tool lets you choose a delimiter for the output, including comma, semicolon, tab, or pipe, and turn nested object flattening on or off. Nested keys are mapped to dot-separated column headers such as user.address.city, and values containing commas, quotes, or line breaks are quoted according to RFC 4180. Before exporting, you can review the result in an interactive table view with sorting, search, and pagination, then copy the CSV or download it as a .csv file.

The page is aimed at developers, data analysts, and spreadsheet users who need to move API responses or database exports into Excel, Google Sheets, Pandas, or SQL tools.
