What is a Text to Line Array converter?

                        
It is a developer tool that transforms plain text (one item per line) into a properly formatted code array. Instead of manually typing quotes, commas, and brackets, you simply paste your list and get instant, ready-to-use code for your project. This saves time and eliminates syntax errors when creating string arrays from spreadsheets, logs, or any line-separated data.

                    

                

                

                    

                        
Which programming languages are supported?

                        
We support 12+ languages including JavaScript/TypeScript, Python, PHP, Java, C#, Ruby, Go, Rust, Swift, Kotlin, Dart, and SQL (IN clause format). Each language follows its idiomatic array syntax — for example, PHP uses $variable prefix, Go requires trailing commas in slice literals, and SQL generates parenthesized IN clause values. Switch between languages instantly to see the output update in real time.

                    

                

                

                    

                        
How are special characters and quotes handled?

                        
The tool automatically escapes quote characters within your text to prevent syntax errors. If you choose double quotes as the wrapper, any double quotes inside the text are escaped with backslashes (\"). For SQL mode, single quotes are escaped using the SQL standard of doubling them (''). You can also select different quote types (single, double, backtick, or none) to match your project's style guide and avoid conflicts.

                    

                

                

                    

                        
Can I use this tool for SQL IN clauses?

                        
Absolutely! Select "SQL (IN Clause)" from the language dropdown. The output format changes to ('value1', 'value2', 'value3') — perfect for pasting directly into your WHERE column IN (...) queries. This is especially useful when you have a list of IDs, usernames, or product codes from a spreadsheet that you need to query against. The tool handles SQL-specific single-quote escaping automatically.

                    

                

                

                    

                        
What does "Remove Empty Lines" do?

                        
When enabled, any line that is completely blank (or contains only whitespace after trimming) is excluded from the output array. This is useful when copying data from sources that have spacing gaps, such as formatted documents, emails, or exported reports. Combined with "Trim Whitespace," it ensures your array contains only meaningful, clean values without accidental empty string elements that could cause bugs in your code.

                    

                

                

                    

                        
Is the generated code production-ready?

                        
Yes. The output follows industry-standard formatting conventions for each language — proper indentation, correct bracket/brace usage, idiomatic variable declaration, and appropriate trailing comma behavior. For instance, Go slice literals always include trailing commas (as required by the language spec), Python follows PEP 8 with 4-space indentation, and PHP uses the modern short array syntax []. You can copy the output directly into your codebase with confidence.

                    

                

                

                    

                        
Can I customize the variable name?

                        
Yes, you have full control over the variable name. Simply type your desired name in the "Variable Name" field. When switching between languages, the tool intelligently adjusts naming conventions — for example, adding a $ prefix for PHP or suggesting snake_case for Python and Ruby. You can override any suggestion to match your project's specific naming conventions or to assign the array to a property, constant, or any valid identifier.

                    

                

                

                    

                        
Does this tool work offline or store my data?
