The same fix, applied to every file in a batch
Renaming a variable, updating a copyright year, or fixing a recurring typo across dozens of files individually is exactly the kind of repetitive task that invites mistakes from fatigue. Applying one rule to every uploaded file at once, with a per-file match count, makes it both faster and more auditable.
Why per-file match counts matter
A file showing zero replacements might mean it never had the issue — or might mean the pattern didn't match due to a formatting difference worth investigating. The count per file, not just a total, makes that distinction visible.
What file types does this support?
Any plain text format — code, Markdown, CSV, JSON, HTML, and CSS all work, since they're all read and processed as text.
Are files modified in place?
No — the original uploaded files aren't changed; you download a new set (or zip) of updated files separately.
Need multiple different rules applied across many files?
Use Multi-File Replace instead, which applies a full list of rules to every file rather than just one.
