IntroductionIn this post you will learn how to extract data from web pages using SSIS. In other words, read HTML Table in SSIS, then Loop through extracted links and finally download files. To achieve this scenario we will use SSIS HTML Source and REST API Task.PrerequisitesBefore we perform the steps listed in this article, you will need to make sure the following prerequisites are met: SSIS designer installed. Sometimes it is referred to as BIDS or SSDT (download it from the Microsoft site). Basic knowledge of SSIS package development using Microsoft SQL Server Integration Services. Make sure ZappySys SSIS PowerPack is installed (download it, if you haven't already). (Optional step). Read this article, if you are planning to deploy packages to a server and schedule their execution later.Step-By-StepTo achieve desired extraction from web pages / download files we have to use few different components. Let’s get started.Read HTML Table from Web PageFirst, let’s read desired content from web URL using SSIS HTML Source. This component can read data from URL(s), Local HTML File(s) or Direct HTML String stored in a SSIS variable.Create a new SSIS ProjectIn the control flow, Right click anywhere in the designer and click Variables option.Create following 3 variables which we will use later on.FileList (Object Type)ZipFileName (String Type)ZipFileUrl (String Type) – Default Value must not be blank (Enter anything like ).Drag Data Flow Task from SSIS Toolbox to designerGo to data flow designer by clicking on the data flow task.Drag and drop ZS HTML Table Source and double click to edit it. Enter the HTML Web Page URL from where you like to read information. For example purpose, we will use below URL. On that page we have a table with files we need to download. Configure – SSIS HTML Table Source URL / Other OptionsNow let’s go to Extract Links and Images tab and check Output Links for each column. This will give us link for Zip File URL which we want to download.Configure SSIS HTML Table Source (Extract Text / Images/ Links from Web Pages / URL)Click Preview to see data.Preview HTML Table DataNow click on OK to save the UI.In next section we will configure Recordset DestinationSave Records to SSIS VariableNow let’s look at how to save HTML Table into in memory recordset which we will loop through later on.

Basic JavaScript Codes to Export HTML Table to Excel Use the TabletoExcel Library to Export HTML Table to Excel in JavaScript Use the TableExport Library to Export HTML Table to Excel File in JavaScript Use the jQuery table2excel Library to Export HTML Table to Excel File in JavaScript Use SheetJS xlsx to Export HTML Table to Excel File in JavaScript Excel spreadsheets serve as the bedrock for organizing and comprehending tabular information in the dynamic landscape of data management.Navigating the transition from HTML tables to Excel sheets is a pivotal skill, facilitating seamless data transfer.This tutorial covers diverse methods that empower you to seamlessly export HTML tables to Excel files, including from foundational JavaScript techniques to powerful libraries.Basic JavaScript Codes to Export HTML Table to ExcelThis method involves crafting a JavaScript function that seamlessly converts an HTML table into an Excel file, ready for download. The approach utilizes native browser features without relying on external libraries. Let’s explore the step-by-step implementation of this approach.First, create the HTML structure that houses the table you intend to export. We will use a simple HTML table with a button to initiate the export process for demonstration purposes.html>head> title>Export HTML Table to Exceltitle>head>body> table id="tableId"> table> button id="exportButton">Export to Excelbutton> script> // JavaScript code will go here script>body>html>Next, let’s implement the JavaScript function responsible for exporting the table to an Excel file. This function leverages the Blob and URL.createObjectURL features to create a downloadable link.function exportTableToExcel(tableId) { // Get the table element using the provided ID const table = document.getElementById(tableId); // Extract the HTML content of the table const html = table.outerHTML; // Create a Blob containing the HTML data with Excel MIME type const blob = new Blob([html], {type: 'application/vnd.ms-excel'}); // Create a URL for the Blob const url = URL.createObjectURL(blob); // Create a temporary anchor element for downloading const a = document.createElement('a'); a.href = url; // Set the desired filename for the downloaded file a.download = 'table.xls'; // Simulate a click on the anchor to trigger download a.click(); // Release the URL object to free up resources URL.revokeObjectURL(url);}// Attach the function to the export button's click eventdocument.getElementById('exportButton').addEventListener('click', function() { exportTableToExcel('tableId');});The JavaScript function exportTableToExcel(tableId) retrieves the HTML content of the specified table using its ID. It then creates a Blob containing the HTML data with the Excel MIME type.A temporary anchor () element is created to hold the URL, and the desired filename. VBA to extract HTML Table data. 0.

Of jQuery functions and methods.Export Trigger: The function Export() takes center stage in initiating the export operation. Invoked through a trigger, this function orchestrates the conversion of HTML table data to an Excel spreadsheet.Selecting the Table: The core of the export process lies in the $("#table") selector. This directive identifies the specific HTML table targeted for export.Customizing Export: The table2excel() method is applied to the selected table within the same function. The filename property is integral to customization, determining the name of the exported Excel file. In this case, the file will be named file.xls.Use SheetJS xlsx to Export HTML Table to Excel File in JavaScriptSheetJS is a powerful JavaScript library that allows for manipulating and converting spreadsheet file formats, including Excel. This library allows developers to effortlessly export data from HTML tables into Excel spreadsheets. Let’s dive into the step-by-step implementation of this approach.To begin, ensure you have the SheetJS library installed. You can add it to your project using a package manager like npm:Next, import the necessary modules in your HTML file:html>head> title>Export HTML Table to Exceltitle> script src=" table id="myTable"> table> script> // JavaScript code will go here script>body>html>Now, let’s create a function to export the HTML table to an Excel file using SheetJS.function exportTableToExcel(tableElement, filename) { const table = document.querySelector(tableElement); const tableData = []; // Extract table data table.querySelectorAll('tr').forEach(row => { const rowData = []; row.querySelectorAll('th, td').forEach(cell => { rowData.push(cell.textContent); }); tableData.push(rowData); }); // Create worksheet const worksheet = XLSX.utils.aoa_to_sheet(tableData); // Create workbook const workbook = XLSX.utils.book_new(); XLSX.utils.book_append_sheet(workbook, worksheet, 'Sheet1'); // Export the workbook to Excel file XLSX.writeFile(workbook, filename);}The exportTableToExcel function takes the HTML table element and a filename as parameters. It first extracts the table’s data into a 2D array. Then, it creates a worksheet using SheetJS’s XLSX.utils.aoa_to_sheet method. The workbook is created by combining the worksheet, and the download is initiated using the XLSX.writeFile method.To trigger the export process, call the exportTableToExcel function, passing the table element’s selector and the desired filename.// Example usageexportTableToExcel('#myTable', 'table_data.xlsx'); Enjoying our tutorials?

How to Extract Tables from HTML with Python and

Web scraping is an invaluable technique for programmers and data analysts who need to extract large datasets from websites. Rather than manually copying and pasting information from HTML pages, scraping allows you to automate the collection of data into structured formats like CSV, JSON, or Excel for further analysis. One of the most common web scraping tasks is parsing and extracting tabular data from HTML tables on pages. Important data like financial stats, sports results, product catalogs, and user directories are often presented in tables on sites.In this comprehensive 2500+ word guide, we‘ll dive deep into expert techniques for scraping HTML tables using the popular Python BeautifulSoup library.The Value of Scraping Tabular DataBefore we dig into the code, it‘s worth understanding why tabular data is such a vital scraping target:Use Cases Across IndustriesMany industries rely on scraping tabular HTML data to power key business functions:E-Commerce – Scrape product details like pricing, images, descriptions, specs into catalogs.Finance – Collect numerical data like stock prices, earnings, ratios for analysis. Sports Analytics – Build datasets of player stats, scores, standings for fantasy sports, betting, etc.Real Estate – Aggregate listings data including price, beds, square footage, amenities.Travel – Scrape flight/hotel comparison tables to monitor price changes.Structured and Relational DataTables present data in an inherently structured format with rows, columns and common fields for each record. This makes scraping tables ideal for outputting clean, consistent datasets ready for import into databases and data warehouses.The row and column format also makes it easier to parse and extract relational data, where different attributes are related to each other for analysis. cleaner Cleaner than Unstructured TextUnlike scraping longform text or reviews, there is less need for complex NLP parsing when extracting structured fields within an HTML table. The data is already atomized for us.Of course, we still need to handle issues like spanning rows and columns, missing values, duplicate records, etc. But overall, scraping tables will involve simpler logic than scraping freeform text from pages.Data rankings, comparisons, indexesAuthors will often present data summaries, rankings and indexes in table format to improve readability. Examples are financial indexes, school rankings,

Id=‘population-table‘)This will return the with a matching id attribute.By Class NameWe can also search for tags by class name:table = soup.find(‘table‘, class_=‘financial-data‘) By CSS Selector More complex CSS selector patterns can also be used to target elements:table = soup.select_one(‘table#data-table‘)The .select() method allows querying with full CSS selectors like table#id or table.class.Multiple TablesFor pages with multiple tags, we may need to iterate through the results of .find_all(‘table‘) or .select(‘table‘) to isolate the one we actually want.Once we‘ve targeted the specific table, save it to a variable for later reference:table = soup.find(‘table‘, id=‘data-table‘)Now let‘s extract the data from our table!Column headers provide valuable context on what each cell of data actually represents. In properly structured data tables, header values are marked up in tags within the first table row.We can loop through the first row and pull out the text from each :headers = []for th in table.find(‘tr‘).find_all(‘th‘): headers.append(th.text.strip()) This will give us a list like [‘Name‘, ‘Age‘, ‘Location‘] that we can use later when extracting the data rows.For more complex tables with spanning/colspan headers, additional logic may be required to associate headers with data columns.With the headers captured, we can loop through the remaining rows and extract each cell value into a list:rows = []for tr in table.find_all(‘tr‘)[1:]: cells = [] for td in tr.find_all(‘td‘): cells.append(td.text.strip()) rows.append(cells)This gives us a list of lists, where each nested list is a row of cell data.If headers were extracted already, we skip the first row to avoid re-parsing the headers. Putting It All TogetherLet‘s tie together the full table scraping process:Initialize BeautifulSoupimport requestsfrom bs4 import BeautifulSouppage = requests.get(‘ soup = BeautifulSoup(page.content, ‘html.parser‘)Find the Tabletable = soup.find(‘table‘, id=‘data-table‘) Extract Headers headers = []for th in table.find(‘tr‘): headers.append(th.text.strip())Extract Rowsrows = []for tr in table.find_all(‘tr‘)[1:]: cells = [] for td in tr.find_all(‘td‘): cells.append(td.text.strip()) rows.append(cells) Print Output for row in rows: print(dict(zip(headers, row)))This gives us a clean set of dictionaries with header keys!There are many options for outputting the structured data – export to CSV, insert into database, transform into pandas DataFrame, etc.Common Table Scraping ChallengesWe‘ve covered the key foundations of scraping HTML tables with BeautifulSoup.
