Burjua the getReport returns a this. The issue I'm having is that the window opens and closes immediately not downloading the file — Braden Brown.
How can we set file name in here? I've used the above code for downloading a file from API response but i'm getting some error in creating the Blob part "Type response is not assignable to type Blobpart". Kindly help if anyone knows this issue — knbibin. Show 10 more comments. Try this! Hector Cuevas Hector Cuevas 1, 1 1 gold badge 6 6 silver badges 3 3 bronze badges. I used step 2 in combination with the answer from Alejandro and it worked without the need to install file-saver Thank you!
It works perfectly! I wonder if we can get the filename that is defined on the header of the response. Is that possible? This one however is not suitable for big files download.
Can someone please tell why this answer is downvoted? The topic is to download a file using angular2. If this method works to do a simple download then it should also be marked as a valid answer. SaurabhShetty, This won't help in case you want to send custom headers, what if you want to send an auth token for example?
If you look into OP question you can see he uses authHttp! I do understand the downvotes, nevertheless this answer solved my issue. If you let the server return the url in some context, the server could prepare the url. The cover could be a url to an image in the server. When calling get Myrecord you let the server return the prepared url Cover , with security token and other headers set. It is an answer that works.

I am sending the filesize as content-length in the http header. How about this? So simple yet it is the one that work flawlessly. It doesn't clutter the DOM, doesn't create any element. I combined this solution with some of the aboves and it works like a charm.
Other examples are included in the showcase. The node version automatically requires modules for additional features. Some of these modules are rather large in size and are only needed in special circumstances, so they do not ship with the core. For browser use, they must be included directly:. Compared to full build:. Webpack and Browserify builds include optional modules by default.
Webpack can be configured to remove support with resolve. Since the library uses functions like Array forEach , older browsers require shims to provide missing functions.
The xlsx. Third-party libraries either supported one format, or they involved a separate set of classes for each supported file type. Emphasizing a uniform object representation enables new features like format conversion reading an XLSX template and saving as XLS and circumvents the mess of classes.
By abstracting the complexities of the various formats, tools need not worry about the specific file type! A simple object representation combined with careful coding practices enables use cases in older browsers and in alternative environments like ExtendScript and Web Workers. It is always tempting to use the latest and greatest features, but they tend to require the latest versions of browsers, limiting usability.
Most simple operations should only require a few lines of code. More complex operations generally should be straightforward to implement. However, there are other formats with more appealing properties.
Even though an XLSX writer is available, other format writers are available so users can take advantage of the unique characteristics of each format. The primary focus of the Community Edition is correct data interchange, focused on extracting data from any compatible data representation and exporting data in various formats suitable for any third party interface. For parsing, the first step is to read the file. This involves acquiring the data and feeding it into the library.
Here are a few common scenarios:. Browsers have no API for reading arbitrary files given a path, so another strategy must be used. The specified path should be an absolute path:. The extendscript demo includes a more complex example. Data from file input elements can be processed using the same APIs as in the drag-and-drop example. The oldie demo shows an IE-compatible fallback scenario. More specialized cases, including mobile app file processing, are covered in the included demos.
Neither format puts the directory structure at the beginning of the file: ZIP files place the Central Directory records at the end of the logical file, while CFB files can place the storage info anywhere in the file! As a result, to properly handle these formats, a streaming function would have to buffer the entire file before commencing.
That belies the expectations of streaming, so we do not provide any streaming read API. When dealing with Readable Streams, the easiest approach is to buffer the stream and process the whole thing at the end.
This can be done with a temporary file or by explicitly concatenating the stream:. This example uses tempfile to generate file names:. This example uses XLSX. The workbook object contains a SheetNames array of names and a Sheets object mapping sheet names to sheet objects. The XLSX. The new workbook is blank and contains no worksheets. The write functions will error if the workbook is empty. The node version installs a command line tool xlsx which can read spreadsheet files and output the contents in various formats.
The source is available at xlsx. Some helper functions in XLSX. For writing, the first step is to generate output data. The helper functions write and writeFile will produce the data in various formats suitable for dissemination. The second step is to actual share the data with the end point.
Assuming workbook is a workbook object:. This example assumes the server can handle Baseencoded files see the demo for a basic nodejs server :. For much older browsers, there are workarounds implemented by wrapper libraries. Note: XLSX. The included demos cover mobile apps and other special deployments. The streaming write functions are available in the XLSX. They take the same arguments as the normal write functions but return a Readable Stream. They are only exposed in NodeJS.
XLSX is the exposed variable in the browser and the exported node variable. SSF is an embedded version of the format library. Parse options are described in the Parsing Options section.
In browser-based environments, it will attempt to force a client-side download. If o is omitted, the writer will use the third argument as the callback. Write options are described in the Writing Options section. Utilities are available in the XLSX. The ranges are inclusive. Utility functions perform a row-major order walk traversal of a sheet range:.
Built-in export utilities such as the CSV exporter will use the w text if it is available. To change a value, be sure to delete cell.
The utilities will regenerate the w text from the number format cell. The actual array formula is stored in the f field of the first cell in the array range. Other cells in the range will omit the f field. The raw value is stored in the v value property, interpreted based on the t type property. This separation allows for representation of numbers as well as numeric text.
There are 6 valid cell types:. Type n is the Number type. Excel exclusively uses data that can be fit in an IEEE floating point number, just like JS Number, so the v field holds the raw number. The w field holds formatted text. That's great! Thanks for the info. Message 10 of Message 11 of Message 12 of ToanDN What about getting rid of the Excel borders? Message 13 of You can't.
