Show HN: Split CSV into multiple files to avoid the Excel's 1M row limitation

  You have a large file (CSV, txt,etc). Let's split its contents into multiple files.

Why is this a yearly cost? I don’t understand.

There’s already open source utilities [0] for users who aren’t proficient in Unix commands.

If anything this should be the definition of a one time fee.

You’re free to charge whatever you like, but it seems odd that anyone would pay you year after year to use your app.

It’s not the price, as $40 isn’t that much, but the value and principle of the thing.

This of course assumes that each line is a single record, so you'll need some preprocessing if your CSV might contain embedded line-ends. For the preprocessing, you can use something like the `2tsv` command of https://github.com/liquidaty/zsv (disclaimer: I'm its author), which converts CSV to TSV and replaces newline with \n.

You can also use something like `xsv split` (see https://lib.rs/crates/xsv) which frankly is probably your best option as of today (though zsv will be getting its own shard command soon)
