Text Filter
Extract Data from Text Instantly
Text Filter lets you extract specific data from any plain text in seconds. Paste your content and choose a filter to get a clean, deduplicated list. All processing happens locally in your browser — your data never leaves your device. No registration, no ads, no limits, forever free.
How to Use
- Paste your text: Enter or paste any raw text into the text area above.
- #Hashtags: Extracts all words prefixed with
#— e.g.,#design,#SocialMedia. Supports Unicode, accented characters, and non-Latin scripts. - Emails: Extracts all valid email addresses found in the text — e.g.,
hello@example.com. - Links: Extracts all URLs starting with
http://,https://, orwww.. - Numbers: Extracts all numeric strings, including decimals and comma-formatted numbers — e.g.,
42,3.14,1,000. - Emojis: Extracts all Unicode emoji characters from the text.
- Horizontal / Vertical: Toggle between results displayed on a single line (space-separated) or stacked one per line. Default is vertical. Switch at any time without re-running the filter.
- Copy: Copies all results currently displayed to your clipboard, ready to paste anywhere.
- Delete: Clears both input and output so you can start a fresh session.
- Theme: Switch between Light, Dark, and Auto to match your preference or device setting.
How It Works
Each filter uses a dedicated Regular Expression to scan the entire input text and collect all matching items. Duplicates are automatically removed while preserving the original order of appearance. Processing is entirely client-side — no server calls, no external libraries, no AI. The result is a clean list ready to copy and use.
