Handle Commas and Line Breaks in Lead CSV Notes
Build a five-record quoted-field fixture, reconcile parsed rows and fields, and preserve research notes without shifting columns or flattening meaning.

A note containing two paragraphs is still one field. A company name containing a comma is still one company name. Trouble starts when a preparation script counts physical lines as records or splits each line at every comma. Valid research notes can then become extra contacts, shifted columns, or truncated explanations.
The objective is to preserve the boundaries between records and fields while keeping the meaning inside each note. Deleting punctuation and line breaks may hide a broken parser, but it also removes useful context. Test the parser rather than flattening every note until the file happens to load.
Establish a three-column contract
For a narrow pilot, use record_key, company_name, and research_note. Each parsed record must have exactly three fields. Define whether the first parsed record is the header, whether an empty note is allowed, and which delimiter the destination expects. Keep these settings with the test file.
RFC 4180 describes double-quoting fields containing commas, line breaks, or quotation marks, and escaping a quotation mark by doubling it inside a quoted field. It is an informational description of common CSV behavior; verify the destination's supported implementation rather than assuming every importer behaves identically.
A spreadsheet export function or maintained CSV library should create the file. Avoid constructing CSV through string concatenation. A replacement rule that surrounds every note with quotation marks but does not escape embedded quotes remains incomplete.
Specify the fixture before producing the file
Use these fictional records as an expected-value ledger. They describe content, not instructions to execute anything.
Q01: company name Elm, Harbor and Co.; note Asked about regional availability, not pricing.
Q02: company name Pine Workshop; note Buyer said “review in November”. Preserve the quotation marks actually chosen in the source.
Q03: company name Lantern Testing; note with paragraph one, “Operating site confirmed”, followed by a line break and paragraph two, “Purchasing owner unverified”.
Q04: company name North Yard; an empty research note.
Q05: company name Cedar Bench; note containing an ordinary double quote and a comma in the same field.
Give the fixture five records excluding its header. The physical file may contain more than six lines because Q03 has an embedded line break. Its correct parsed record count remains five. Record that distinction in the expected outcome so an automated line counter does not create a false incident.
The quoted-field test file can be represented as follows. The line break inside Q03 belongs to its quoted note, not to a sixth record.
record_key,company_name,research_note
Q01,"Elm, Harbor and Co.","Asked about regional availability, not pricing."
Q02,Pine Workshop,Buyer said “review in November”.
Q03,Lantern Testing,"Operating site confirmed
Purchasing owner unverified"
Q04,North Yard,
Q05,Cedar Bench,"Review label: ""provisional"", purchasing owner unverified."
Reconcile structure before judging content
Parse the saved file with the intended settings. Check the header names, five distinct keys, and three fields for every record. Compare each decoded field with the ledger. The parser should return the content without CSV's enclosing quotation marks or doubled escape characters.
Next, import the fixture into an isolated destination and inspect all five notes. Confirm that Q03 remains attached to its company and that its second paragraph has not become an independent row. Check Q04 separately: an empty note may mean no update, a cleared property, or another configured behavior. The test must state the intended action instead of treating blank content as automatically harmless.
Export the destination records and parse them again. The exported serialization may use different legal quoting while representing the same content. Compare field values and record associations, not whether the raw files look identical.
Diagnose a shifted row without guessing
In an illustrative failure, Q01's company name arrives as Elm and the research-note field contains Harbor and Co. The expected number of fields has changed. That points toward serialization or parsing, not a salesperson choosing the wrong company. Quarantine the affected batch and inspect the first malformed record using a safe text viewer.
Do not repair the destination by shifting every column after the first comma. Some rows will have no embedded comma, and others may contain several. Regenerate from the controlled source with correct escaping, then rerun the complete fixture. Preserve evidence of which production rows were already written before retrying.
The usable acceptance checklist is short: expected parsed records, expected fields per record, exact key set, decoded field comparison, empty-field behavior, and destination association. Assign an owner to each failure. When all checks pass, retain the fixture and parser settings for future exports. The test demonstrates structural integrity, not that the notes are accurate, current, or permitted for the intended use.
