Hey there! I totally get wanting that convenient table-style CSV editing experience in the Community Edition without upgrading to Ultimate—been in that exact spot before. Here are some reliable alternatives I’ve tested or seen recommended by other developers:

• CSV Plugin
  This is the go-to replacement for most folks. It adds a full-featured table view for CSV files, letting you edit cells directly, sort columns, filter rows, and adjust column widths to your liking. Any changes you make in the table view sync automatically back to the original CSV file, so you don’t have to mess with manual conversions. Just search for "CSV Plugin" in IDEA’s Plugin Marketplace, install it, restart IDEA, and you’ll see an option to switch to table view when opening a CSV file.

• Rainbow CSV
  While it’s known for color-coding CSV columns to improve readability, Rainbow CSV also includes a robust table editor. It supports features like column renaming, data validation (to catch syntax issues), and even basic spreadsheet-like functions. It’s lightweight and works seamlessly with Community Edition—find it in the Plugin Marketplace too.

• Temporary Database Tools Workaround
  If you need more advanced data manipulation occasionally, you can use IDEA Community Edition’s built-in Database Tools to treat your CSV like a temporary database table. Here’s how:

  1. Open the Database tool window (if it’s hidden, go to View > Tool Windows > Database).
  2. Click the + icon, select File Data Source, and choose your CSV file.
  3. Configure the delimiter, encoding, and header settings to match your CSV.
  4. Once set up, you can edit the data in a table interface just like a database table, then export the changes back to CSV when you’re done.

A quick tip: After installing any of these plugins, keep an eye on the top-right corner of your editor window when opening a CSV file—there should be a button to switch between plain text and table view.
