Developer text tools built for real copy-and-paste workflows.
Convert newline text into SQL IN clauses, quote values for JavaScript arrays, escape JSON strings, inspect Base64 payloads, and clean query parameters without leaving the browser.

Why DevFormat
DevFormat should feel like a focused workbench, not a directory of disconnected utilities. The home page starts with a usable tool, then shows the product axes that connect the rest of the cluster.
Text Transform
Encoding & Structured Text
Cleanup & Extraction
Preset-driven first
Start with SQL IN, JS Array, JSON escape, or Base64 decode instead of building a format from scratch every time.
Browser-only workflow
Small text transformations stay local to the browser, which keeps the loop fast and avoids sending copied values to a server.
Related tasks stay connected
A user who starts with quoting often also needs joining, escaping, JSON validation, or URL encoding in the same session.
Cleanup before transform
Repeated values, mixed notes, and side-by-side list checks now have their own cleanup category before you move into formatting or encoding.
Popular workflows
Search traffic is usually tied to a concrete job. These are the strongest entry points for the current tool cluster.
Build a SQL IN clause from raw values
Paste multiline values, apply the SQL preset, and copy a query-ready output.
Clean exports and compare noisy lists
Remove duplicate lines, trim copied rows, extract numbers, and compare two lists before moving into quoting or encoding.
Prepare safe payload text for requests
Escape a JSON string, URL encode a parameter, or inspect Base64 when request layers stack together.
Clean text for URLs, configs, and code
Split a joined string, slugify a label, or format JSON before it lands in an API client or config file.
Core tool cluster
Once the first transformation is done, users usually need a second or third step. The catalog stays below the hero so the landing page first behaves like a product, then like a directory.
Newline to SQL IN Clause
Turn multiline values into SQL IN clauses, JavaScript arrays, Python lists, CSV rows, or custom joined output.
- Popular intent: text to SQL IN clause
- Preset examples for SQL, JS, Python
- Reverse mode for joined strings
Create a custom formatter
Build your own text formatting recipe with custom delimiters, wrappers, quotes, and saved browser-only presets.
- Save formatter recipes locally
- Apply the same recipe across repeated workflows
- Share current formatter settings by link
Quote Each Line Online
Wrap every value with quotes, backticks, or CSV-friendly delimiters, then strip the quotes back out when needed.
- Popular intent: quote each line online
- Single quote, double quote, backtick presets
- Unquote mode for cleanup
Newline to Comma-Separated List
Join or split clean values with comma, pipe, tab, space, newline, or a custom separator.
- Popular intent: newline to comma separated list
- Delimiter-only conversion
- Trim and skip-empty options
Escape String for JSON
Escape quotes, slashes, tabs, and newlines for JSON or JavaScript strings, then unescape the result when you need raw text back.
- Popular intent: escape string for JSON
- JSON, JS, regex presets
- Unescape mode included
Base64 Decode String Online
Decode copied Base64 payloads or encode UTF-8 text directly in the browser while debugging tokens, headers, and payloads.
- Popular intent: base64 decode string online
- UTF-8 safe conversion
- Encode and decode modes
URL Encode Query Parameter
Encode query parameter values, decode request fragments, and inspect URL-encoded payloads without touching a CLI utility.
- Popular intent: url encode query parameter online
- Encode and decode modes
- Useful for API debugging
Slugify Text and Convert Case
Turn raw text into slugs, kebab-case, snake_case, camelCase, PascalCase, or CONSTANT_CASE with one input field.
- Popular intent: slugify text online
- Case conversion presets
- Useful for URLs and identifiers
JSON Formatter and Validator
Validate, prettify, and minify JSON to inspect payloads before they move into requests, configs, or logs.
- Popular intent: json formatter and validator
- Validation feedback
- Pretty and minified output
Remove Duplicate Lines
Keep the first occurrence of each value and drop repeated lines from copied text, exports, and config lists.
- Popular intent: remove duplicate lines online
- Order-preserving output
- Trim and skip-empty cleanup
Extract Emails from Text
Pull email addresses out of mixed notes, logs, CSV exports, and support tickets without sending text to a server.
- Popular intent: extract emails from text
- Unique-only and sort-output toggles
- One address per line
Compare Two Lists
Paste two newline lists and copy common values, only-in-A values, or only-in-B values for debugging and QA.
- Popular intent: compare two lists online
- Intersection and difference output
- Works with IDs, env keys, and exports
Use cases people actually search for
Related tools are the product
Each page is designed to lead to the next likely task. If a user arrives for newline-to-comma conversion, the site should also make it obvious when quoting, escaping, URL encoding, or JSON formatting are natural next steps.
How-to guides for long-tail search
These guides target people searching for a concrete output or cleanup action like a SQL IN clause, JavaScript array, JSON-safe escaped string, blank-line removal, number extraction, or CSV column cleanup.
Newline text to SQL IN clause
Turn one value per line into a query-ready IN (...) list for IDs, emails, or spreadsheet exports.
Text to JavaScript array
Convert newline text into ["value1", "value2"] output with quotes, commas, and brackets already applied.
Text to Python list
Generate Python list output from one-value-per-line text with quotes and brackets already applied.
Newline text to CSV row
Turn one value per line into a CSV-style row for exports, imports, and spreadsheet cleanup.
Escape string for JSON
Convert quotes, tabs, newlines, and backslashes into JSON-safe string content before a value goes into an API payload or config file.
Quote lines for SQL values
Add single quotes around each line before joining the values into SQL-ready output.
Split a comma-separated list into lines
Turn a comma-separated row back into one value per line before dedupe, cleanup, or quoting.
Text to env var list
Turn one value per line into a deployment-friendly comma-separated env var string.
Newline to Markdown bullet list
Convert plain lines into clean Markdown bullets for docs, tickets, and release notes.
Create a custom text formatter
Build your own reusable output recipe with custom delimiters, wrappers, quotes, and browser-only saved recipes.
Share formatter settings without sharing text
Copy a recipe link so the same formatter setup can be reopened later or shared with a teammate without exposing input values.
Remove empty lines from text
Delete blank rows from copied text, logs, exports, and notes before quoting, comparing, or joining the remaining values.
Trim whitespace from lines
Remove leading and trailing spaces from each line so copied values are normalized before dedupe, compare, or quote workflows.
Extract numbers from text
Pull integers and decimals out of logs, copied notes, and mixed exports, then reuse the clean values in compare or formatting tools.
Extract a column from CSV
Turn CSV, TSV, or delimited rows into one value per line by selecting a column and copying the result directly in the browser.
Frequently asked questions
Does DevFormat send text to a server?
No. The current tools run in the browser, which keeps the workflow fast and avoids round trips for small transformation tasks.
Why start with text tools instead of generic utilities?
Because text workflows chain together. A user who quotes values may also need multiline conversion, delimiter cleanup, string escaping, JSON validation, or URL decoding in the same session.
What should be indexed first?
Index the home page and each tool page separately. The tool pages target concrete search intent, while the home page explains the cluster and routes users toward related tasks.
