   CSV GB+ by Data.olllo – Open and Process CSVs Locally▲51

   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…

    Privacy-first cross platform spreadsheet pipeline app▲17

    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…
