Eu escrevi um produto chamado Editor do Ron que você pode querer ver. Eu estou sempre interessado em torná-lo mais útil / poderoso, então eu estaria interessado em seu feedback.
Ron's Editor is a powerful CSV file editor. It can open any format of
separated text, including the standard comma and tab separated files
(CSV and TSV), and allows total control over their content and
structure.
With a clean and neat interface Ron's Editor is also ideal to simply
view and read CSV, or any text delimited, files.
Ron's Editor is the ultimate CSV editor, whether you need to edit a
CSV file, clean some data, or merge and convert to another format,
this is the ideal solution for anyone who regularly works with CSV
files.
