Jan 22, 2018

Webscraping is een gecompliceerde techniek geïmplementeerd met een aantal scraptools. Deze hulpprogramma's werken op dezelfde manier samen met verschillende websites als bij het gebruik van een browser zoals Firefox of Chrome. Bovendien geven web scraping programma's de geëxtraheerde gegevens weer in een leesbaar formaat. Ze helpen bij het genereren van meer leads en halen het beste uit onze bedrijven.

De beste webschrapingstools:

Hier hebben we een lijst met beste en nuttigste webscrapingtools gegeven, waarvan sommige gratis zijn terwijl de anderen worden betaald.

1. Import.io

Import.io is beroemd om zijn geavanceerde technologie. De tool is geschikt voor professionals en niet-professionals. Deze webscraping-tool benadert en schraapt niet alleen een groot aantal websites, maar exporteert ook de geëxtraheerde gegevens naar CSV. Honderden tot duizenden pagina's en PDF-bestanden kunnen binnen een uur met Import.io worden geschraapt. Het pluspunt is dat je geen code hoeft te schrijven. In plaats daarvan bouwt dit hulpprogramma meer dan 1000 API's op basis van uw vereisten.

2. Dexi.io

Dexi.io staat ook bekend als CloudScrape. Dit webschraping en data-extractieprogramma is geschikt voor programmeurs en freelancers. Het is algemeen bekend om zijn browser-gebaseerde downloader en editor die het voor u gemakkelijk maakt om de geëxtraheerde gegevens op uw harde schijf te openen en downloaden. Dit is ook een geweldige webcrawler die de gegevens op Box.net of Google Drive kan opslaan. U kunt uw gegevens ook exporteren naar CSV en JSON.

3. Webhouse.io

Webhouse.io is een van de meest verbazingwekkende en fantastische browsergebaseerde webschrapingstoepassingen, biedt eenvoudige en directe toegang tot de gestructureerde gegevens en heeft de mogelijkheid om enorme aantallen webpagina's te indexeren in de enkele API.U kunt eenvoudig uw gegevens extraheren met Webhouse.io en opslaan in indelingen zoals RSS, XML en JSON.

4. Scrapinghub

Met slechts $ 25 per maand kunt u toegang tot alle verbazingwekkende functies van Scrapinghub. Dit is een cloud-gebaseerde applicatie die beter voldoet aan uw vereisten voor het extraheren van gegevens. Scrapinghub is vooral bekend om zijn slimme proxy-rotator die gemakkelijk door de bot-beschermde websites kruipt.

5. Visual Scraper

Visual Scraper is nog een ander programma voor data-extractie en content mining: het extraheert informatie van verschillende websites en de resultaten worden in realtime opgehaald. U kunt uw geëxtraheerde gegevens exporteren naar formaten zoals SQL, JSON, XML en CSV.

Het is een Firefox-add-on die onze webzoekopdracht aanzienlijk kan vereenvoudigen vanwege zijn eigenschappen voor gegevensextractie. Outwit Hub is even beroemd bij programmeurs en webontwikkelaars; deze tool slaat uw gegevens op in leesbare en schaalbare formaten en biedt een gebruikersvriendelijke interface en de beste services.

7. Scraper

Het is waar dat Scraper beperkte mogelijkheden heeft om gegevens te schrapen, maar dat betekent niet dat het uw online onderzoek niet gemakkelijk maakt. In feite is Scraper de eerste keuze van verschillende bedrijven, SEO-experts en app-ontwikkelaars. U kunt gegevens kopiëren naar het klembord of opslaan op verschillende spreadsheets volgens uw wens. Helaas kruipt dit hulpmiddel uw webpagina's niet.

8. 80 poten
