Data export

Web Scraper browser extension supports data export in CSV and XLSX formats while Web Scraper Cloud supports data export in CSV, XLSX and JSON formats. A JSON format will be added to the Web Scraper extension in a future release.

Data export from Web Scraper Extension

Download scraped data via Export data as CSV menu selection under the Sitemap menu. Data can be also downloaded while the scraper is running.

Automated data export

Set up automated data export to Dropbox, Google Sheets or S3 via the Data Export section. Currently exported data will be in CSV format. Data will be exported to Apps/Web Scraper in your Dropbox , Google Drive/Web Scraper in Google Sheets and bucket/web-scraper in S3.

Data export via API

Additionally, you can download data via Web Scraper Cloud API in CSV or JSON formats.

Data format file structure and limitations


Data in separate cells is limited to 32767 characters. Additional characters will be cut off. Use other export formats if large text contents are expected in a single cell. The row count is limited to 1 million rows. In case the data set contains more than 1 million rows, the data will be split into multiple sub sheets.

Fig. 4: JSON Data format


JSON file format contains one JSON record per line. Newline characters found in data will be escaped as "\n" so \n character can be safely used as a record separator.

Note! Parsing the entire file as a JSON string will not work since all records are not wrapped in a JSON array. This was a design decision to make it easier to parse large files.

Comma Separated Values files format is formatted as described in RFC 4180 standard. Values are quoted in double-quotes " and in a case when a double-quote character is in the text it is escaped with another double-quote character. Lines are separated with CR+LF \r\n characters. Additionally CSV files include byte order mark (BOM) U+FEFF characters at the beginning of the file to hint that the file will be in UTF-8 format. Newline characters are not escaped which means using \r\n as a record separator can result in errors. We recommend using a CSV reader library when reading CSV files programmatically.

Opening CSV file with a spreadsheet program

We recommend using Libre Office Calc when opening CSV files. Microsoft office often is incorrectly interpreting CSV files formatted in RFC 4180 standard. Mostly this is related to text including newline characters.

In case when a CSV file is incorrectly opened by Microsoft Excel try using data import feature:

  1. Start with an empty file
  2. Go to the Data tab
  3. Choose From Text/CSV

  4. Open CSV file
  5. Set up import settings - UTF-8 encoding, Comma delimiter, Do not detect data types

  6. Load data
