Spreadsheet Companion
FreeCSV/XLSX Tooling
Edit CSV/TSV files in a real table and view XLSX workbooks: without leaving the IDE, and without the plugin taking over your files.
The gap it fixes
The leading paid spreadsheet plugin ($39/year, ~307K downloads) has half its reviews at 3 stars or fewer. Paying users report they can't add or delete rows, can't copy/paste cells, that the plugin forcibly takes over CSV files with no opt-out, that its license prompt freezes the whole IDE, and that it corrupted XLSX files on save.
