Regex Data Extractor
Batch extract data matching patterns using regular expressions.
Tool Guide
Introduction to the Online Regex Data Extractor
The Online Regex Data Extractor batch-extracts target content from text using regular expressions. It's suitable for scenarios such as phone number extraction, order number extraction, email extraction, and ID extraction.
The matching rule supports one capture group: if the rule contains a group, the group content is output first; if there is no group, the full match content is output. You can combine it with "deduplicate" to quickly complete data cleaning.
Key Features
1. Batch Regex Extraction
Supports batch-extracting target fields from large blocks of text according to rules, improving manual filtering efficiency.
2. Group Extraction Capability
You can use groups to keep only the key fragment, avoiding extracting extra prefix or suffix text.
3. Result Deduplication and Export
Supports a deduplication toggle. After extraction, you can copy the results in one click or download them as a TXT file.
How to Use the Regex Data Extractor
Step 1: Enter the regex matching rule (may include one group).
Step 2: Choose whether to deduplicate.
Step 3: Paste the text to be processed and click "Start Processing."
Step 4: View the number of extracted results and copy or download TXT as needed.
Use Cases
Suitable for scenarios such as log text extraction, customer data cleaning, batch field scraping, and development debugging and test data organization.
FAQ
Why was no data extracted?
Usually because the regex rule doesn't match the text format. We recommend verifying step by step with a simpler expression first.
What's the difference between group extraction and whole-match extraction?
Group extraction returns only the content matched within the parentheses; whole-match extraction returns the entire matched text.
Does it support multi-line text extraction?
Yes. You can directly paste multiple lines of data for batch processing.
