Configuration
Complete the Word: Suffix Power for Extensions & Tags
When managing hundreds of filenames, database fields, or word lists, adding consistent endings manually is tedious and error-prone. Need to add .jpg extensions to a list of image names? Want to pluralize every word (mechanically) with an "s"? Need to tag variables with _old or _backup for code versioning? These tasks take minutes when done one-by-one but are instant with bulk suffix processing.
The Add Suffix to Words tool automates word-ending modifications. It offers four wrapping styles (None, Brackets, Quotes, Custom), word filtering to skip short words, case transformation options, and file upload/download support. Whether you're organizing file libraries, creating versioned code copies, or formatting data exports, this tool processes thousands of words in seconds while preserving your document's spacing and line breaks.
Why Add Suffixes to Words?
- ✓File Management: Add extensions (.txt, .jpg, .pdf) to filename lists for batch file creation, library organization, or script automation.
- ✓Code Versioning: Append version markers (_old, _new, _backup, _v2) to variable names, function identifiers, or database column names during migrations.
- ✓Data Formatting: Add plural markers, category tags, or unit labels (kg, m, s) to word lists for database imports or CSV processing.
- ✓Batch Renaming Prep: Prepare file lists with consistent suffixes before running bulk rename scripts or folder reorganization operations.
Common Use Cases
File Library Organization
Add file extensions (.jpg, .png, .pdf) to lists of filenames for batch file creation. Perfect for photographers managing image libraries, designers organizing assets, or developers preparing file manifests for scripts.
Database Migrations
Append version suffixes (_v2, _old, _backup) to database column names during schema migrations. Create parallel table structures before deprecating old columns, ensuring safe rollback options.
Data Export Formatting
Add unit labels (kg, m, USD) or category tags to CSV export columns. Prepare data for import into analytics platforms, ERP systems, or e-commerce databases with consistent field naming.
Package Management
Add version numbers or environment tags (prod, dev, test) to package names, module identifiers, or npm package lists for dependency management and deployment automation.
