Radio Weather Services

NWR is a nationwide network of radio stations broadcasting continuous weather information directly from the nearest National Weather Service (NWS) office. It is often referred to as "All-Hazards" because it broadcasts warnings for more than just natural disasters like tornadoes and flash floods; it also covers environmental hazards like oil spills and national emergencies.

One sharp idea each week to help you handle messy spreadsheets, weird exports, and undocumented CSVs — faster and smarter.

News  25th Apr, 2025: Tablecruncher goes Open Source!

Features

Open files bigger than 2GB and containing more than 15 million rows. Opening a 100MB CSV file with more than 500,000 lines takes less than 5 seconds on a dual-core Macbook Pro.
Use Javascript as a macro language to manipulate your CSV files. A simple API gives you access to all cells and you can change cell content as well as do abitrary calculations.
Export your table data to JSON. The exported JSON is an array-of-objects if there's a header row present in your CSV data. Otherwise you'll get an array-of-arrays.
🗃
Automatically detects most CSV file formats and file encodings for you. If you want, you can easily override the automatic detection and choose the appropriate CSV parameters.
📄
Open and save CSV files with one of these encodings: UTF-8, UTF-16LE, UTF-16BE, Latin-1 (ISO-8859-1) and Windows 1252 files. (These list will be extended in future updates.)
🔎
Use the powerful Find and Replace dialog to search for patterns in your table or in a selected area. Regular Expressions according to the ECMAScript 5 standard are supported.
🎨
Enjoy crunching your data with four beautifully designed color themes, including a dark theme that fits well with the Mac's dark mode.
𝌘
Flag rows manually or with the Find and Replace dialog and export flagged rows as a new CSV file.
𝌅
Modify your CSV data grid easily. You can sort lines alphabetically or numerically, move columns right or left or delete columns. Or set your first CSV row as a header row.
