Stand-Alone Spreadsheet Components

First of all, let us go through JS libraries that are primarily intended to contribute to faster integration of a feature-packed spreadsheet into a web app.

DHTMLX Spreadsheet

DHTMLX Spreadsheet is a fully customizable JavaScript spreadsheet component with a convenient API for processing tabular data of any complexity. It has an intuitive Excel-like interface adaptable to touch devices. With this library in your dev stack, you get a lot of features for productive working in spreadsheet tables. Besides common grid operations, you can enable users to freeze rows & columns, lock/unlock cells, create drop-down lists with validation, autofill cells with data, apply text-wrapping, sort columns and data ranges, and much more. A user-friendly toolbar (ribbon) with multiple controls will aid users in formatting and styling specific cells.

There is a regularly updated collection of more than 250 built-in functions compatible with Excel and Google Sheets that can be used to manipulate string and numeric data within a cell or range. It is also possible to arrange data in separate worksheets and, when needed, combine data from various sheets into one with the help of cross-referencing via available formulas. DHTMLX Spreadsheet supports a range of predefined number formats with adjustable settings and allows creating custom ones. The spreadsheet interface is also adaptable to various languages. The table navigation is facilitated with a large list of hotkeys. The final version of your document can be converted to Excel format.

All functional benefits of this library are backed up by flexible licensing with affordable prices varying from $599 to $2899. Thus, you can consider DHTMLX Spreadsheet as a product with a good price/quality ratio. Apart from that, you may be interested in reviewing other DHTMLX components for implementing various functionalities required in business apps.

Handsontable

Handsontable is primarily known as a JavaScript grid library for business apps but the decision to include it in this article is not accidental. Although this tool doesn't offer as many text formatting options as Excel, it includes quite a lot of features for manipulating data typical of spreadsheets. The list of the most widely used Handsontable features includes operations on rows & columns (moving, hiding, resizing, freezing), CRUD actions, non-contiguous selection, data validation, export to file, and merging cells. You can also take advantage of more advanced capabilities such as multi-column sorting, data summaries, trimming rows, and nested headers.

With numerous supported cell types such as date, time, dropdown, password, you’ll give users more freedom for working with cell content. To specify the way users will edit data, you can utilize a predefined cell editor or create a custom one. But how does Handsontable address one of the key functions of any business spreadsheet, namely math calculations? To enable users to perform different kinds of calculating operations in your app, you can utilize a separate Formulas plugin based on the HyperFormula calculation engine specifically designed by the Handsontable team. If you have your own ideas on how to make the Handsontable grid tool more effective, you can create custom plugins.

The Handsontable library has a lot of good qualities in terms of functionality that certainly boosts its price. To obtain this tool for web development, you’ll have to fork out from $899 per developer.

Jspreadsheet PRO

Jspreadsheet PRO (previously known as Jexcel) is an Excel-like spreadsheet plugin notable for its real-time collaboration feature. It offers such essential functionality as text formatting, frozen columns, data filtering, sorting, and searching.

Similar to popular spreadsheet software, Jspreadsheet allows utilizing built-in and custom formulas and performing cross-worksheet calculations. The plugin supports several native editors that can be complemented with custom options to enhance the user experience in data editing. Jspreadsheet lacks some of the common built-in features like keyboard navigation, data validation, and value formatting. However, you can put into action third-party extensions or set up your own add-ons to achieve your goals.

This JavaScript tool is provided in Base and Premium editions via monthly ($39/$119), yearly ($390/$1,190) subscription or one-time purchase (3699$). The premium edition includes extra features, plugins, extensions, priority tech support, and other goodies.

SpreadJS

SpreadJS is a multifaceted Excel-inspired solution designed and maintained by GrapeCity to become a strong response to most of modern data handling demands on the web. When exploring its extensive feature-set, it may be hard for many to immediately name any Excel feature that is not supported by this widget.

First of all, SpreadJS is known for its powerful calculation engine with a large collection of functions of different types for performing complex computations when preparing various business documents. There are many features that will help you to expand users’ abilities in working with cells. For example, you can add cell buttons, barcodes, apply rich text, rotate text in cells, auto merge cells, and much more. To offer a deeper insight into your spreadsheet data, it is possible to add pivot tables, charts, sparklines, tables. An auxiliary desktop design tool named SpreadJS Designer offers a code-free way to quickly create a complex spreadsheet layout or load your existing Excel .xlsx template files and get down to work with data right away.

Everything seems to be great in SpreadJS but there is one important factor that may discourage you to buy this product. It is about high associated expenditures. The thing is that you’ll have to pay not only for a developer license but also for a hostname deployment license. Such a bundle will cost you at least 1499$ per developer. GrapeCity also provides the Wijmo library that can be used in combination with SpreadJS for building a consistent business app much faster.

Webix Spreadsheet

Webix Spreadsheet is a JavaScript UI widget designed to speed up the integration of a multifunctional spreadsheet table into your web project. It is probably one of the most advanced tools included in the Webix UI library. Spreadsheets built with Webix can be equipped with features to which many users have grown accustomed in the desktop Excel. They are built-in math functions, manipulations with rows and columns, sorting and filtering, editing, various types of data, etc.

The widget allows enriching the cell content with sparklines, images, as placeholders. The ability to leave comments in cells will help to avoid any ambiguities. You can also enable such useful functions as cell merging and conditional cells formatting. At times, users may need to focus just on the presented information, that is where the capabilities to hide the headers of rows and columns and greedlines will come in handy. If none of the built-in functions can help you to perform a required operation, it is possible to create a custom one for this purpose. After users finish using the spreadsheet, they export it to PDF/PNG and Excel or activate the printing function to get the hard copy of the table.

If you decide that the Webix Spreadsheet widget is the right tool for your project, then you can consider several licenses with different pricing options floating from $798 to $9,499. Moreover, Webix also offers a pack of UI controls that will be a great addition to the spreadsheet widget.

How to start an electric scooter facility/fleet in a university campus/IT park

Are you leading an organization that has a large campus, e.g., a large university? You are probably thinking of introducing an electric scooter/bicycle fleet on the campus, and why wouldn’t you?

Introducing micro-mobility in your campus with the help of such a fleet would help the people on the campus significantly. People would save money since they don’t need to use a car for a short distance. Your campus will see a drastic reduction in congestion, moreover, its carbon footprint will reduce.

Micro-mobility is relatively new though and you would need help. You would need to select an appropriate fleet of vehicles. The people on your campus would need to find electric scooters or electric bikes for commuting, and you need to provide a solution for this.

To be more specific, you need a short-term electric bike rental app. With such an app, you will be able to easily offer micro-mobility to the people on the campus. We at Devathon have built Autorent exactly for this.

What does Autorent do and how can it help you? How does it enable you to introduce micro-mobility on your campus? We explain these in this article, however, we will touch upon a few basics first.

Micro-mobility: What it is

You are probably thinking about micro-mobility relatively recently, aren’t you? A few relevant insights about it could help you to better appreciate its importance.

Micro-mobility is a new trend in transportation, and it uses vehicles that are considerably smaller than cars. Electric scooters (e-scooters) and electric bikes (e-bikes) are the most popular forms of micro-mobility, however, there are also e-unicycles and e-skateboards.

You might have already seen e-scooters, which are kick scooters that come with a motor. Thanks to its motor, an e-scooter can achieve a speed of up to 20 km/h. On the other hand, e-bikes are popular in China and Japan, and they come with a motor, and you can reach a speed of 40 km/h.

You obviously can’t use these vehicles for very long commutes, however, what if you need to travel a short distance? Even if you have a reasonable public transport facility in the city, it might not cover the route you need to take. Take the example of a large university campus. Such a campus is often at a considerable distance from the central business district of the city where it’s located. While public transport facilities may serve the central business district, they wouldn’t serve this large campus. Currently, many people drive their cars even for short distances.

As you know, that brings its own set of challenges. Vehicular traffic adds significantly to pollution, moreover, finding a parking spot can be hard in crowded urban districts.

Well, you can reduce your carbon footprint if you use an electric car. However, electric cars are still new, and many countries are still building the necessary infrastructure for them. Your large campus might not have the necessary infrastructure for them either. Presently, electric cars don’t represent a viable option in most geographies.

As a result, you need to buy and maintain a car even if your commute is short. In addition to dealing with parking problems, you need to spend significantly on your car.

All of these factors have combined to make people sit up and think seriously about cars. Many people are now seriously considering whether a car is really the best option even if they have to commute only a short distance.

This is where micro-mobility enters the picture. When you commute a short distance regularly, e-scooters or e-bikes are viable options. You limit your carbon footprints and you cut costs!

Businesses have seen this shift in thinking, and e-scooter companies like Lime and Bird have entered this field in a big way. They let you rent e-scooters by the minute. On the other hand, start-ups like Jump and Lyft have entered the e-bike market.

Think of your campus now! The people there might need to travel short distances within the campus, and e-scooters can really help them.

How micro-mobility can benefit you

What advantages can you get from micro-mobility? Let’s take a deeper look into this question.

Micro-mobility can offer several advantages to the people on your campus, e.g.:

• Affordability: Shared e-scooters are cheaper than other mass transportation options. Remember that the people on your campus will use them on a shared basis, and they will pay for their short commutes only. Well, depending on your operating model, you might even let them use shared e-scooters or e-bikes for free!
• Convenience: Users don’t need to worry about finding parking spots for shared e-scooters since these are small. They can easily travel from point A to point B on your campus with the help of these e-scooters.
• Environmentally sustainable: Shared e-scooters reduce the carbon footprint, moreover, they decongest the roads. Statistics from the pilot programs in cities like Portland and Denver showimpressive gains around this key aspect.
• Safety: This one’s obvious, isn’t it? When people on your campus use small e-scooters or e-bikes instead of cars, the problem of overspeeding will disappear. you will see fewer accidents.
