Free Excel to JSON Converter

There are many articles that explain how to convert data from an Excel spreadsheet into a JSON format. This is because the data in a JSON format can be easily read by a web application. It can also be easily converted back into Excel format if needed.

What's JSON File Form?

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. - It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language independent but uses conventions that are familiar to programmers of the C-family of languages (C, C++, JavaScript, etc.). These properties make JSON an ideal data-interchange language.

Can Excel generate JSON file?

You would need to use a third-party tool or write a custom script to generate a JSON file from Excel data.

How do I convert an Excel file to JSON?

The process of converting Excel to JSON is fairly simple. You can convert or export excel to json ( xls to json , xlsx to json...) - Manually, - the data in the Excel spreadsheet is exported to a CSV file. - Next, the CSV file is converted to a JSON file using a online converter tool. - Finally, the JSON file is imported into the web application. - Using a Free Converter Excel to Json Online: - Excel To json Converter The JSON format is very popular for web applications because it is easy to read and understand. It is also easy to convert back to Excel if needed. Read the full article

Debunking Ecommerce Tracking

People will share a lot of their thoughts about eCommerce monitoring with you, whether you're just starting out or already in the thick of things. Or perhaps you have some thoughts on how to operate an online ecommerce. However, odds are that the most of them are incorrect. But don't worry—we're here to assist you.

What is Ecommerce Tracking? 

Google Analytics' Ecommerce Tracking tool keeps tabs on online purchases made through your website. It can be used to monitor and examine sales data, revenue, sold goods, and more.

You may learn a lot about your website's readership and traffic through GA. You may get quantifiable information on what users are doing on your site from metrics like exit, bounce, and goal conversion rates as well as insights on audience demographics, landing page views, and more.

Debunking Tracking Challenges

Google Analytics isn’t accurate

Due to the nature of how internal systems and analytics gather data, discrepancies will always occur.

The majority of analytics tools rely on JavaScript and cookies to track site visits, and while this approach generates a consistent stream of recorded data, it will never be ideal. The issue is that we have no control over what the user does. Both Google Analytics and other programmes won't be able to track a user if they disable cookies or JavaScript.

It's also critical to realise that the accuracy of the data will be impacted by the use of Google Analytics. It won't be able to record these if the code isn't included on every page of your website. Similar to how inaccurate coding can impact measures and dimensions, the real figure may be overstated or underreported.

Exporting data is difficult

It's really easy to export data from Google Analytics. In addition to being easy to use, a user can choose from a variety of forms. By choosing the export option at the top of each report page, a user can export up to 5,000 rows of any report they are seeing.

Six distinct file types, including CSV, TSV, TSV for Excel, Excel (XLSX), Google Spreadsheets, and PDF, can be used to export the data.

There is too much information to report on with any clarity.

It's understandable that many potential or new GA users are intimidated by the enormous volume of data that it can collect. Many customers believe that it will be challenging to locate the precise information they need within the interface and which reports they will need to employ.

However, I believe that GA excels in this area because it is practical and simple to understand. Knowing what each reporting component contains only requires a top-level understanding of where items can be found.

Except for real-time reporting, the four primary reporting parts are:

Audience 

Traffic Sources 

Content 

Conversions 

Segmentation is too complicated

There are a number various ways to segment data that Google Analytics offers, all of which are simple to use. Creating specialised profiles with fine-grained filters that only allow the data you're looking for to populate the profile is the initial method of segmenting data.

Utilizing the sophisticated features that are offered within the interface is the second strategy. The vast majority of reports can use these. The two types of advanced segments are default segments (which are made publicly available) and custom segments, which can be made to display only the data you want to see.

Skipping to track shopping cart abandonment rate

The proportion that represents the number of sessions with cart abandonment is known as the cart abandonment rate. Understand how much potential money you're losing by using the cart abandonment metric.

The Conversions > Ecommerce > Shopping Behavior report contains information about the cart abandonment rate for your store.

In India, e-commerce is undergoing rapid change. Since it's barely been around for 13 years, there are a lot of misconceptions about it. Learn about the business and your customers so that you can analyse it effectively. This will provide you plenty of chances to expand your company and avoid any dangers.

nitic ctf writeup

nitic ctfに参加したので解いた順にwriteupを残しておく。 運営の皆様ありがとうございました。

1. web meta ダウンロードしたhtmlファイルのヘッダからフラグ取得。

2. long_flag $ curl -o long_flag.html https://quizzical-mcnulty-e4cdbf.netlify.app/ でページソースを取得するとspanタグに挟まれたフラグが1文字ずつ見える。 $ sed -e 's/<[^>]*>//g' long_flag.html を実行してタグを取り除いてフラグ取得。

3. pwn_monster 1 ncするとゲーム開始。 何が動くのか理解するために、一回そのまま動作させてみる。 名前を入力すると、nameの左に16進数で名前のasciiコードが出てきてゲーム開始。 入力フィールドが名前しかないので、規定文字数以上入れると他の数値を書き換えられると考えて、 fff....ff という入力を作成。無事hp, attackのパラメータを巨大な数にしてフラグ取得。 先にソースコードを読んで、構造体を理解して...というのが理想的なフラグ取得であろうと思われる。

4. excel excel（拡張子xlsx）は実体がzipだと分かっていたため、 ダウンロードしたexcelの拡張子をzipに変更して展開。展開したディレクトリの中で $ find ./ -type f -print0 | xargs -0 grep nitic を実行してフラグ取得。

5. Caesar Cipher タイトルから2文字ずらせば良いかなと考えた��失敗。 エンコード済み文字列から以下のようにアルファベットを順に並べて、目視で有意な文字列を探す力業でフラグ取得。 rnckpvgzv sodlqwhaw tpemrxibx plaintext qmbjoufyu

6. protected ダウンロードしたファイルを展開して $ file chall   chall: ELF 64-bit LSB shared object, x86-64, ... ELFとのことで実行バイナリと判定。 $ strings chall で有用そうな情報はないか探してみる。 ここで実行時のパスワード文字列が平文で保持されていた。 バイナリを実行するとパスワードを求められるので先のパスワードを入力してフラグ取得。

7. image conv 液晶を斜めに覗くとフラグヘッダが見えたのでgimpでコントラストを調整してフラグ取得。

8. ord_xor エンコードプログラムを読み込んでxorでエンコードされていると理解。 xorは二回適用するともとのデータに戻るので、プログラムの実行内容から $ export FLAG=ENCODED_FLAG  #バッククォートは\でエスケープ $ python3 enc_sample.py $ cat flag としてフラグ取得。

9. pwn_monster 2 チェックサムがあるが、オーバーフローしてチェックサムを実現すれば良いと理解。 単純にhp、attackを7f ff ff ff ff ff ff ffにするとチェックサムが-1となってしまう。 ここで発想を逆転してattackをマイナス値にして敵hpを（回復させることで）オーバーフローさせれば良いと気がつく。 あとは計算した値をechoでパイプ渡ししてフラグ取得。

反省 1. Crypto: tanitu_kanjiで解決までの道筋が見えていても短時間でプログラムに落とし込むまでの力が不足していた。 2. python、javascriptについてのスキルが全体的に不足。 3. スタックオーバーフローについて概要は分かっていても実践に移せていないので、実践できるよう練習が必要。 4. writeupの書き方として、公開すべき情報と隠蔽すべき情報の境界を見極めたい。

Web Scraper Chrome Extension

We created a browser extension which uses AI to detect tabular or listing type data on web pages. Such data can be scraped into CSV or Excel file, no coding skills required. Our extension can also click on the “Next” page links or buttons and retrieve data from multiple pages into one file. The extension runs completely in user’s browser and does not send data to Web Robots. When testing it we benchmarked that this tool would work with the Amazon, Ebay, Bestbuy, Craigslist, Walmart, Etsy, Home Depot, Yellow Pages, etc. – it works on all of them.

Instant Data Scraping Extension We created a browser extension which uses AI to detect tabular or listing type data on web pages. Such data can be scraped into CSV or Excel file, no coding skills required. Our extension can also click on the “Next” page links or buttons and retrieve data from multiple pages into one file. The basic idea of web scraping is that we are taking existing HTML data, using a web scraper to identify the data, and convert it into a useful format. The end stage is to have this data stored as either JSON, or in another useful format.

How to use it:

Open the first page of listing results (products, directory, etc) in your browser

Activate the extension

Extension will guess where your data is. If not happy use “Try another table” button to guess again.

Download CSV or Excel from the first page if that is all you need. Or click to locate “Next” button to mark the “Next” link/button on a website.

Click “Start crawling” to start crawling through multiple pages a website. Extension will show statistics on what is being collected.

Download Excel or CSV file at any time during the crawl.

Clean up Excel or CSV files – it will most likely have some unwanted additional fields that were extracted from the page. Most likely column names will have to be renamed as well.

Try another table – AI guesses an alternative table if the initial guess was not what you want.

Locate “Next” button – press this and mark the location of “Next” button or linked on a website. This will be used to scrape data from multiple pages into one file.

Crawl delay – time in seconds before going to the next page. Default value is 1 second. it can be increased when pages load information dynamically.

CSV and XLSX – file download buttons. They are active right away when any data is found.

Infinite Scroll – extension can scroll down on pages where more data is loaded dynamically. It automatically detects when loading new data stops.

At Web Scraper we are solving problems that people hate - manual, repetitive work.

With more than 400k users in the Chrome Store, Web Scraper is the most popular data extraction solution in Chrome extension store. Our goal is to become the industry standard for online data gathering. You should be a part of this.

Phishing de Microsoft Office 365 evade la detección

Una campaña de phishing reciente utilizó un truco inteligente para entregar la página web fraudulenta que recopila las credenciales de Microsoft Office 365 mediante la construcción de fragmentos de código HTML almacenados local y remotamente. El método consiste en pegar varias piezas de HTML ocultas en archivos JavaScript para obtener la interfaz de inicio de sesión falsa y pedirle a la víctima potencial que escriba la información confidencial. Las víctimas recibieron un correo electrónico con solo un archivo adjunto que afirmaba ser un archivo de Excel (.XLSX) sobre una inversión.

 E.@. Los investigadores de Trustwave decodificaron el texto y encontraron más decodificación por delante, ya que se ofuscó aún más a través de los códigos de entidad. Usando CyberChef de GCHQ, revelaron enlaces a dos archivos JavaScript alojados en "yourjavascript.com", un dominio utilizado para otras campañas de phishing. Cada uno de los dos archivos JavaScript tenía dos bloques de texto codificado que ocultaban el código HTML, la URL y la codificación Base64. 

En total, los investigadores decodificaron más de 367 líneas de código HTML repartidas en cinco fragmentos entre los dos archivos JavaScript y uno en el archivo adjunto del correo electrónico, que, apilados juntos, crearon la página de phishing de Microsoft Office 365. "Esto ayuda a los atacantes a eludir las protecciones de seguridad como Secure Email Gateways que podrían identificar el JavaScript malicioso del archivo adjunto inicial y bloquearlo", agregaron los investigadores. 

La dirección de correo electrónico de la víctima se completa automáticamente para dar una sensación de legitimidad. Las estafas de phishing también comprueban que la contraseña no esté en blanco y utilizarán expresiones regulares para confirmar una dirección de correo electrónico válida.
