# Array Grouper Group array elements based on various criteria such as length, alphabetical order, numeric ranges, custom conditions, and more > Canonical page: https://elysiatools.com/en/tools/array-grouper - **Category:** Development - **Keywords:** array, group, categorize, classify, organize, partition, cluster, bucket ## Overview The Array Grouper is a versatile utility designed to organize and classify data elements into structured buckets based on specific criteria such as numeric ranges, string length, alphabetical order, or fixed group sizes. ## Inputs - **Array Elements** (textarea): Enter array elements separated by delimiter... apple, banana, orange, grape, mango, peach, kiwi, 123, hello@test.com - **Input Delimiter** (select) - **Custom Delimiter** (text): Enter custom delimiter - **Grouping Method** (select) - **Group Size** (number): Elements per group (e.g., 3) - **Numeric Range Size** (number): Range interval for numeric values (e.g., 10) - **Alphabetic Group Count** (number): Number of alphabetical groups (e.g., 6) - **Length Ranges** (text): Comma-separated lengths (e.g., 5,10,15,20) - **Case Sensitive** (checkbox) - **Preserve Original Order** (checkbox) - **Output Format** (select) ## When to use - When you need to partition a large list of items into smaller, manageable chunks for processing. - When you want to categorize raw data into logical segments like numeric intervals or alphabetical clusters. - When you need to clean and organize unstructured input data into a clean JSON, CSV, or table format. ## How it works - Paste your list of elements into the input field and select the appropriate delimiter used in your data. - Choose a grouping method, such as Fixed Size, Numeric Ranges, or String Length, to define how the tool should cluster your items. - Adjust the specific parameters for your chosen method, such as range intervals or group size, to refine the output. - Select your preferred output format, such as a formatted table or JSON, and generate the organized result. ## Use cases - Segmenting customer IDs or product codes into fixed-size batches for database imports. - Organizing a long list of names alphabetically into specific buckets for directory generation. - Grouping numeric sensor readings into defined ranges to identify data trends or outliers. ## Frequently asked questions ### What input delimiters are supported? The tool supports commas, spaces, new lines, semicolons, and custom delimiters to ensure compatibility with various data sources. ### Can I group numbers by specific intervals? Yes, by selecting the 'Numeric Ranges' grouping method, you can define a range interval to bucket numbers accordingly. ### Does the tool preserve the original order of elements? Yes, you can enable the 'Preserve Original Order' checkbox to maintain the sequence of your input data within the groups. ### What output formats can I export? You can export your grouped data as a formatted table, JSON, CSV, visual representation, or a simple summary. ### Is the grouping case-sensitive? Yes, you can toggle the 'Case Sensitive' option to determine whether uppercase and lowercase letters are treated as distinct during classification. ## Related tools - [Array Element Deleter](https://elysiatools.com/en/tools/array-element-deleter): Delete specific elements from arrays with support for multiple deletion methods - [Filename Sanitizer](https://elysiatools.com/en/tools/filename-sanitizer): Clean and sanitize filenames by removing illegal characters for Windows, Linux, and Mac - [A/B Test Significance Calculator](https://elysiatools.com/en/tools/ab-test-significance-calculator): Compute conversion-rate or mean differences, 95%/99% confidence intervals, two-sided p-values (Z-test for proportions, Welch t for continuous metrics), lift, sample size for 80%/90% power, recommended experiment days, plus sequential-testing and Bonferroni multiple-comparison warnings. - [AI Markdown Article Translator](https://elysiatools.com/en/tools/ai-markdown-article-translator): Translate full Markdown articles with AI while preserving headings, tables, links, images, and code blocks for direct publication - [Array Shuffle](https://elysiatools.com/en/tools/array-shuffle): Randomly shuffle array elements with support for different shuffling algorithms and reproducible results - [Red Cell Distribution Width (RDW) Analyzer](https://elysiatools.com/en/tools/rdw-analyzer): Analyze Red Cell Distribution Width (RDW) with MCV to help differentiate anemias. RDW-CV reference ≈ 11.5–14.5%, RDW-SD ≈ 39–46 fL (lab-dependent). Elevated RDW reflects anisocytosis. Classic Bessman patterns: high RDW + low MCV → iron deficiency anemia (IDA), which raises the RDW early — before MCV/Hb fall; normal RDW + low MCV → thalassemia trait (uniform microcytosis). Other patterns: high RDW + high MCV → megaloblastic anemia (B12/folate), MDS, drugs, hemolysis with reticulocytosis, preleukemia, or mixed populations (combined iron + B12 deficiency, post-transfusion); high RDW + normal MCV → early/mixed nutritional deficiency, dimorphic anemia, marrow recovery; normal RDW + normal MCV → anemia of chronic disease is classically normocytic. Interpret with Hb, ferritin, Hb electrophoresis, and clinical context. Based on Bessman 1983 and Teixeira 2014.
