Line Counter

Count lines in text online — Line Counter

Quickly count lines in any text block. This simple online line counter returns the total number of lines (including empty lines), plus helper counts you can use in cleanup workflows. Use it to check list sizes, CSV rows, code snippets, or any multiline text.

How to use

• Paste your text into the editor.
• Click the Line Counter action (or the corresponding button in the UI).
• Read the totals shown by the tool: total lines (empty lines included), and helper values for further processing.

Behavior & limits

• Every line is counted. Empty lines (blank lines) are counted as lines in the total.
• If you need the number of non-empty lines, run Remove Empty Lines first and then count again.
• To get the number of unique lines, combine this tool with Remove Duplicates and then recount.
• There is no published hard limit — the tool can process as much text as your browser can handle (memory and CPU permitting).
• The counter works with standard newline separators (LF/CRLF) and treats each separated line as one item.

Examples

Example 1 — simple list with a blank line

Input:
apple
banana

orange

Total lines: 5
Non-empty lines (after removing empty lines): 3
Unique lines (after removing duplicates): 3

Example 2 — list with duplicates

Input:
item1
item2
item1
item3

Total lines: 4
Unique lines (after Remove → Duplicates): 3

Build workflows — common pipelines

• Count only meaningful rows: Remove Empty Lines → Line Counter.
• Get unique row counts: Line Counter → Remove Duplicates → Line Counter.
• Prepare CSV rows for import: paste CSV → Trim → Remove Empty Lines → Line Counter.
• Extract items, dedupe and sort: use Pattern Extractor or URL Extractor, then Remove Duplicates, then Alphabetize List.

Tips & edge cases

• If your text uses unusual separators, normalize line breaks (convert CRLF/LF) before counting.
• Short example testing: run the count on a small sample to confirm how empty or whitespace-only lines are treated.
• Large files depend on browser capacity — for very large datasets consider splitting input or using a desktop tool.

FAQ

Are empty lines included in the total?

Yes. Each line is counted, including blank/empty lines. To exclude empty lines, run Remove Empty Lines before counting.

How can I count only unique lines?

Use Remove Duplicates to strip duplicate lines, then run the Line Counter again to get the unique-line count.

Does the tool handle CSV rows?

Yes — the tool treats each newline as a row. For CSV-specific processing (parsing columns or converting), use converters like CSV → JSON after counting if needed.

Is there a limit to how much text I can count?

There’s no fixed server-side limit documented — processing capacity depends on your browser and device. If the input is very large, split it or use local tools.
