What delimiters does the List Parser support?

The List Parser supports comma (,), semicolon (;), slash (/), pipe (|), backslash (\), and space as delimiters. You can switch between them using the delimiter dropdown.

Can I remove duplicate items from my list?

Yes. Toggle the Deduplicate switch and all duplicate entries will be removed, keeping only the first occurrence of each unique value.

What output formats are available?

You can export your parsed list as a JSON array, CSV, one item per line, numbered list, SQL IN clause, XML, or YAML.

How does the numeric filter work?

The min/max filter keeps only items that are valid numbers within the specified range. Non-numeric items are excluded when a numeric filter is active.

Does the List Parser work offline?

Yes. All processing happens entirely in your browser. No data is sent to any server, and the tool works without an internet connection.

Can I sort the list items?

Yes. You can sort alphabetically (A-Z or Z-A) or numerically (ascending or descending). Non-numeric items are placed after numeric ones when using numeric sort.

List Parser

Parse, count, sort, filter, and reformat lists of IDs or values

DevToolKit's List Parser takes a raw list of IDs or values separated by commas, semicolons, pipes, slashes, backslashes, or spaces. It counts elements, removes duplicates, sorts, filters by text or numeric range, and reformats into JSON, CSV, SQL IN, XML, YAML, or plain text. Runs 100% in-browser.

What is the List Parser?

The List Parser is a browser-based tool designed for developers who frequently work with raw lists of IDs, values, or tokens. Whether you have a comma-separated list from a database query, a pipe-delimited export, or IDs pasted from a spreadsheet, this tool instantly parses, counts, deduplicates, sorts, filters, and reformats them into the structure you need. It supports six common delimiters and seven output formats including JSON arrays, SQL IN clauses, and YAML. All processing happens in your browser — your data never leaves your machine. This makes it ideal for working with sensitive data like user IDs, order numbers, or access tokens that shouldn't be pasted into online tools with server-side processing.

How to Use the List Parser

Paste your raw list into the input area (e.g., 111, 344, 5455, 56, 7675).
Select the delimiter your list uses — comma is the default.
Toggle Deduplicate to remove duplicate values, or change the Sort order.
Expand Filters to include/exclude items by text pattern or numeric range.
Choose your desired output format from the dropdown on the output panel.
Click Copy to copy the formatted output, or Download to save it as a file.
