About these tools
Opening a data file to check one thing should not require installing an application, and a spreadsheet will often damage a CSV on the way in — leading zeros stripped, long numbers rounded, dates reinterpreted. These viewers show a file as it is.
The viewers handle the details that cause the most trouble in practice: encodings detected rather than assumed, semicolon-separated files recognised, quoted fields containing newlines parsed correctly, and deeply nested structures presented as a tree you can collapse.
The comparison tools answer the other common question — what changed between these two, and do I have the same file twice under different names. Duplicates are found by content rather than by filename, which is the only way that answer is worth anything.
