Text Sorter & Deduper

This "Text Sorter & Deduper" is a free browser-based tool that lets you instantly organize multi-line text data. You can perform list sorting (alphabetical, Gojuon, by length, etc.) and bulk removal of unnecessary duplicate lines with a single click.

It is highly effective for tasks that require text formatting, such as organizing customer lists, aggregating survey results, and cleaning data during programming. Furthermore, it offers robust options to automate tedious manual work, like removing empty lines and trimming leading/trailing whitespace.

With its secure local processing design, your input text data is never transmitted to an external server. You can safely use it to organize highly confidential rosters, customer data, or internal company information without any privacy concerns.

Sort

The process of arranging data according to specific rules. This tool supports sorting in alphabetical order (A to Z), Gojuon order, by character length, or in random order.

Deduplication

The process of detecting identical data (lines) within a list, keeping only one instance, and deleting the rest. It's essential for preventing aggregation errors or sending mistakes caused by duplicate data.

Trimming

The process of removing unnecessary whitespaces (such as spaces or tabs) at the beginning and end of each text line. It's useful for clearing out invisible spaces accidentally introduced during data entry.

Ascending / Descending

Ascending (A-Z) orders items from smallest to largest values, while Descending (Z-A) does the reverse. In Japanese, progressing from "A" to "N" is considered ascending order.

Case Sensitivity

A setting that determines whether "Apple" and "apple" are treated as different strings. Disabling this distinction allows for accurate duplicate detection and list organization, even with inconsistent casing.

Q.Is it safe to input confidential data like customer lists?

Yes, it is completely safe. This tool processes all text entirely within your device's browser. Your data is never sent to or stored on external servers.

Q.How many lines of text can be processed?

It depends on your device's memory performance, but generally, texts of several tens of thousands of lines can be processed in a few seconds. Extremely large datasets might cause slight performance slowdowns.

Q.Can it sort Japanese Kanji by phonetic reading (Gojuon order)?

This tool sorts based on character codes (Unicode), so it won't sort Kanji in phonetical (Gojuon) order as expected. For accurate Gojuon sorting, you should convert all Kanji to Hiragana/Katakana before processing.

Q.Why would I want to sort randomly?

Random sorting is useful when you want to eliminate ordering bias. For example, it is very convenient for randomizing survey options to avoid sequence bias, or for creating fair draws and groupings.

Q.When should I use the 'Ignore case' option?

For instance, if your email list contains both 'User@Example.com' and 'user@example.com', enabling this option allows the tool to treat them as identical and correctly remove duplicates.
