Still on my wishlist, but it is promising. The smaller kindles don't let me see enough of PDFs for technical sections.

I have a new tool that has been rolling around in my head for a while. CSV Template Merge. There are many times when I've had to take a list of data and output repetitive code/data. There are many ways to do this, but it felt more challenging to set up than I wanted. With this tool, it should be much easier. You can set up what each item will output using a JavaScript template that is edited inline. You don't have to write the code and can see updates quickly. And because of how you set up the templates, it can use the full power of JavaScript.

One area where this would provide a lot of day-to-day use is formatting data for SQL scripting. As a simplified example, I have the CSV input.


and the template

insert into users (name, dob, active)
values ('${name}', '${dob}', ${active === 'true' ? 1 : 0});

Once merged, you'll get insert statements like this.

insert into users (name, dob, active)
values ('John', '1/1/2000', 1);

insert into users (name, dob, active)
values ('Jane', '1/1/2001', 0);

insert into users (name, dob, active)
values ('Bob', '1/1/2002', 1);

I like it this way because you're not dealing with a lot of manual replacement, excel string concatenation, or regex manipulation. I hope others also find this to be useful.

Have a great day!
