Hey just thought I’d throw it out there, I found an awesome candidate for an external table editor that is lightweight, quick, can open MASSIVE files, and is very versatile / intuitive.
It’s even got fancy features like selecting and editing multiple cells at once, quick reordering of rows / columns or moving of cells / blocks of cells (alt+arrow keys) and will update it’s view instantly when the file is changed elsewhere.
I’ve found that if you link a table DAT to a .TSV file and turn on File Sync, it’s super easy to go back and forth between TD and Modern CSV and the changes almost sync instantly: you still have to press CTRL+S in ModernCSV, but I put in a feature request for instant saving along with the already implemented instant re-loading.
I’m certainly not being paid to shill for this, but I’ve been looking for a modern csv / tsv editor for YEARS and appearantly all I had to do was type that into google. It does cost ~$25USD to unlock some of the more advanced features (and obviously, support the creator), but for the most part everything you could want for working with TD is free forever (no trial periods).
