Features and specs

What each product offers, as listed by its team.

SheetRender 8 features
Lua 6 features
  • Template from an example
    Upload a finished document, even a PDF or a screenshot, and SheetRender infers its layout and builds the template. No merge tags to place.
  • One PDF per row
    Every spreadsheet row becomes its own separate, named PDF file, not one long merged document.
  • Plain-language edits
    Adjust the generated template by describing the change. No drag-and-drop builder and no code.
  • Data Sources
    CSV or XLSX upload, or a Google Sheets snapshot.
  • Print-Ready Output
    A4, Letter and Legal, with real page breaks and correct print margins.
  • Scheduled Runs
    Pick a cadence and the latest rows are pulled, rendered and delivered automatically.
  • Email Delivery
    Send each finished document to an address taken from a column in the sheet.
  • Free PDF Tools
    Merge, split and extract pages, or split a mail merge PDF into named files. Runs in the browser, no upload or account.
  • Easy to Embed
    Lua is designed to be embedded within applications. It has a simple C API which allows it to be integrated easily with C, C++ and other languages.
  • Small Footprint
    Lua is lightweight, with a small memory footprint. This makes it ideal for use in resource-constrained environments, such as embedded systems and game development.
  • Fast Performance
    Lua is known for its high performance due to its efficient interpreter and just-in-time compilation capabilities provided by LuaJIT.
  • Simplicity
    The syntax of Lua is simple and clean, making it easy to learn and use. It's designed to be both powerful and simple.
  • Extensibility
    Lua can be extended through libraries written in C or other languages, allowing for a lot of flexibility and functionality expansion.
  • Dynamic Typing
    Lua uses dynamic typing, which can make code more flexible and easier to write without the need for explicit type definitions.

Possible disadvantages

  • Limited Standard Library
    The standard library in Lua is relatively small compared to other programming languages, which can result in the need for additional third-party libraries.
  • Niche Use Case
    Lua is not as widely adopted for general-purpose programming compared to other languages such as Python or JavaScript, which might limit community support and resources.
  • Error Handling
    Lua's error handling mechanisms are somewhat rudimentary compared to languages that offer advanced exception handling like Python or Java.
  • Lack of Type Safety
    While dynamic typing offers flexibility, it also introduces the risk of type errors at runtime, as type mismatches can only be discovered during execution.
  • Concurrency Limitations
    Lua does not have inherent support for multithreading or concurrency within the language itself. It relies on external libraries or specific environments to handle such tasks.

Questions & Answers

As answered by people managing SheetRender and Lua.

What makes your product unique?

SheetRender's answer

Every other mail merge tool starts by asking you to rebuild your document as a template full of merge tags. SheetRender starts from the finished document instead. You show it one example, a certificate or invoice or offer letter you already have, and it works out the layout and builds the template for you.

The other half is the output. Every row in your spreadsheet comes out as its own separate PDF file, correctly named, rather than one long document you then have to split by hand.

Why should a person choose your product over its competitors?

SheetRender's answer

Two reasons, and they are narrow ones. If you already have a document you like, you can skip template building entirely, which is the step where most people give up on tools like Autocrat or Form Publisher. And if what you need is one file per person rather than one merged document, that is the default here instead of a workaround.

If you are comfortable building templates with merge tags, or you want a PDF generation API to call from your own code, something like PDFMonkey or CraftMyPDF is a better fit. SheetRender is aimed at the person who has a spreadsheet and a deadline, not at a developer.

How would you describe the primary audience of your product?

SheetRender's answer

Non-technical people who own a spreadsheet and need one document per row. In practice that is HR and operations staff sending offer letters, trainers and course administrators issuing certificates to a whole cohort, and small business owners producing invoices or quotes from a billing sheet.

The common thread is that they are not developers, they already have a document that looks right, and the job is repetitive enough to hurt but not big enough to justify building something custom.

What's the story behind your product?

SheetRender's answer

It came from watching people hit the same wall. Someone in HR or training would have a perfect certificate or offer letter in front of them, and a spreadsheet of names, and the tool they were told to use would ask them to rebuild that document from scratch as a template with merge fields in it. Plenty of them stopped there and did it by hand, one at a time.

The question was whether the template step could be removed rather than made easier. If the finished example already contains the layout, software should be able to read it. That turned out to be the interesting problem, and the product grew around it.
