Common use cases
Below are a few common scenarios where JavaScript Formatter is useful:
- Cleaning up input before sharing it with teammates
- Preparing assets for websites, apps, or client deliverables
- Reducing file size and improving performance for end users
- Converting formats so they work in more tools and systems

More tips for better results
When you use JavaScript Formatter regularly, you will get the best results by building a small checklist. For example, confirm the input format, run the tool once, and quickly review the output before using it in production. This reduces mistakes and keeps your workflow predictable.
Another good habit is to keep your source material separate from your processed outputs. If you later need to change quality settings, re-run the conversion, or debug an unexpected edge case, having the original input makes it much easier to reproduce the result.
Finally, treat these tools as building blocks. Many tasks are best solved by combining two or three steps. You might compress first, then convert formats, or format data first, then validate it. The /tools directory makes it easy to discover the next step in your workflow.
