24 alternatives to CSV GB+ by Data.olllo – Open and Process CSVs Locally
I built CSV GB+ by Data.olllo, a local data tool that lets you open, clean, and export gigabyte-sized CSVs (even billions of rows) without writing code. Most spreadsheet apps choke on big files. Coding in pandas or Polars works—but not everyone wants to write scripts just to filter or merge CSVs. CSV GB+ gives you a fast, point-and-click interface built on dual backends (memory-optimized or disk-backed) so you can process huge datasets offline. Key Features: Handles massive CSVs with ease — merge, split, dedup, filter, batch export Smart engine switch: disk-based "V Core" or RAM-based "P…

Hello HN. I've always found writing data visualisation scripts boring and repetitive in data science workflows earlier in my career, so I built this tool to automate it. The available methods are based on my experience in econometrics where histograms and scatterplots were the starting points to check data distributions. The link is to the documentation and the app is freely available at https://visprex.com, and if you're curious about the implementation it's open source at https://github.com/visprex/visprex. I'd appreciate any comments and feedback!

Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

In my previous role at a small startup, I frequently developed simple scripts to assist recruiters and marketing professionals in handling data processing tasks on Excel or CSV files. These tasks were typically straightforward and repetitive, stemming from the periodic export of data. This experience sparked the idea to create a straightforward tool dedicated to such functionalities(also mobile friendly, as they occasionally need to process data on their smartphones). There are powerful tools like Power Query and Tableau, but they often prove too complex for non-technical users to navigate…

SmoothCSV▲11Hi HN, I'm kohii, a software engineer from Japan. I've been building CSV editors for 15 years. This is my third rewrite from scratch, built with Tauri, Rust, and web technologies. *Why I built this:* Modern dev tools, that I use daily, are incredibly polished. CSV editors, not so much. I wanted a tool that handles CSVs as they are (messy column counts, various encodings, any delimiter or quoting style), preserves the original format, and gives you a polished spreadsheet UI with thoughtful UX. *What SmoothCSV does:* - *Fast*: Opens 100MB files in 1.6 seconds. (12x faster than Excel) -…
