Opening a HEAPSNAPSHOT File

The HEAPSNAPSHOT file type is primarily associated with Chrome DevTools.

HEAPSNAPSHOT	File extension: HEAPSNAPSHOT
	File type:	JSON memory snapshot file

What is a HEAPSNAPSHOT file?

HEAPSNAPSHOT files mostly belong to Chrome DevTools.

HEAPSNAPSHOT files are JSON-based dumps that record the state of JavaScript memory during a run. They are generated by Chrome DevTools when you take a memory snapshot.
These files capture details such as object allocations and reference chains.
Key uses include:

Inspecting memory allocations
Detecting memory leaks
Analyzing object references

FilExt.com note: To view a HEAPSNAPSHOT, open Chrome DevTools and use the Memory panel to load the file. More details can be found at Chrome DevTools documentation.

How to open HEAPSNAPSHOT files

You need a suitable software like Chrome DevTools to open a HEAPSNAPSHOT file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your HEAPSNAPSHOT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a HEAPSNAPSHOT file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert HEAPSNAPSHOT files:

Chrome DevTools
See the previous paragraphs to learn more about the main application. HEAPSNAPSHOT files are often referred to as Chrome DevTools developers because this type of file is primarily created or used by this software.
Chrome DevTools
A *.HEAPSNAPSHOT file stores a snapshot of the JavaScript heap memory. It's saved in a JSON format and contains information about JavaScript objects and their relationships, allowing developers to analyze memory usage and identify potential memory leaks. This snapshot is created at a specific point in time and reflects the memory state of the application at that moment. The snapshot includes details about object sizes, references between objects, and the call stack that led to object allocation. Analyzing heap snapshots can help optimize memory consumption and improve the performance of web applications. This file format is classified as Debugging/Profiling.

HEAPSNAPSHOT file format:

The file format determines how the data is stored in the file. Often, the file format can be deduced from the file extension or the initial bytes (called the signature). Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. Knowledge is power - this also applies when dealing with unknown or faulty files. In the following you will find our evaluation of the HEAPSNAPSHOT files:

As a file extension, HEAPSNAPSHOT isn't very common and is primarily used by a single program. The following file formats are most commonly found in HEAPSNAPSHOT files:

96% of all HEAPSNAPSHOT files internally utilize the JSON file format. JSON (JavaScript Object Notation) is a lightweight data−interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. The contents of these files are easily readable with a text editor. A typical file size is 18 MB. This file type is new and state-of-the-art. Certain words are almost always found in the files, such as {"snapshot":{"meta":{"node_fields":["type","name","id","self_size","edge_count","trace_node_id","detachedness"],"node_types":[["hidden","array","string","object","code","closure","regexp","number","na and native. The file name Heap-20180601.heapsnapshot is characteristic of these files. Files like these are sometimes connected to heapdump and profile.

The remaining 4% of all HEAPSNAPSHOT files are different files with different signatures. If you want to find out which format your HEAPSNAPSHOT file belongs to, just click on the button "Choose your .heapsnapshot file to analyze".

How to solve problems with HEAPSNAPSHOT files

Associate the HEAPSNAPSHOT file extension with the correct application.
Update your software that should actually open json memory snapshot files. Because only the current version supports the latest HEAPSNAPSHOT file format. Search, therefore, e.g. on the manufacturer website after an available Chrome DevTools update.
To make sure that your HEAPSNAPSHOT file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
