PREFLIGHT CHECK
Detect malformed quoting and row-width changes caused by commas, newlines or double quotes in ColorMe CSV files.
Analysis stays in your browser; the file itself is not sent to BlueprintLab.

Live service-side state, account-specific settings, remote server reachability and current master data are not asserted. Always prefer the latest official service information.
Check ColorMe CSV structure for commas, embedded line breaks, malformed quoting and row-width shifts.

They are valid inside a CSV field when quoted correctly. The failure happens when quoting changes where the parser thinks a field or row ends.
This checker reports CSV-parser structure errors and row-width mismatches against the header.
The goal is not to delete every comma. Keep legitimate punctuation in product text and fix the CSV quoting around it; validly quoted commas and line breaks can remain in the data.
CSV represents a quote inside a field as `""`. Spreadsheet software often handles this automatically, but hand-edited CSVs are easy to break here.
The checker uses the parsed file rather than searching for quote characters blindly.
Treat the result as a preflight check, not a guarantee that the platform will accept the upload. Account state and current admin settings can add conditions that a browser-only checker cannot prove.
An unclosed quote can absorb a line break and make later rows appear shifted.
Start with the earliest parser error when tracing a malformed file.
A structurally valid CSV can still use the wrong ColorMe product format.
