Mileage and Price Formatting Errors That Fail Posts

The Tahoe is priced. The odometer is in the jacket. The CSV opened in Excel and "looked right." Marketplace rejects the post, or worse, accepts a price with an extra zero and a mileage with a comma that became two numbers. The associate swears he typed what the desk said. He did. The field did not want what he typed.

Mileage and price formatting errors that fail posts are not merchandising debates. They are type errors: commas, dollar signs, decimals, spaces, "K," and cells Excel already helpfully reformatted as dates. They fail the submit, they produce live ads that look like bait, and they generate the kind of buyer messages you cannot recover with a friendly reply. This is adjacent to extra zeros and missing digits, but the failure mode here is broader: anything that makes a numeric field not a clean integer.

This guide is for inventory admins, internet directors, and used-car managers who own the DMS export. No invented "Facebook character limits." Check how Marketplace currently accepts those fields. Your job is to send clean integers every time.

Why Mileage and Price Formatting Errors That Fail Posts Survive "It Looked Fine"

Excel is a display layer. Marketplace is a form. Those are not the same language.

What the form typically wants

A price field wants a number. A mileage field wants a number. What humans type instead:

• $18,990
• 18,990.00
• 18990.00
• 18.9k
• 18990 OBO
• 118,432 miles with a comma
• 118432 miles
• 118k
• A blank that Excel shows as a hyphen
• A cents column from an accounting export (1899000 meaning $18,990.00)

Any of those can fail validation, get truncated, or land as a value you will not honor on the driveway.

Why failed submit is the lucky outcome

A rejected post is annoying. A live post at $189,900 or 118 miles on a five-year-old truck is a reputation event. Shoppers message, joke, report, or show up expecting the lie. You then edit in public. Prevent the format error and you prevent that afternoon.

Where the characters come from

• DMS export with currency formatting turned on.
• A manager who types commas because that is how prices are spoken.
• Copy-paste from a website that includes $ and /mi.
• A row where mileage was never captured in recon and someone typed TBD.
• An odometer replacement note stuffed into the mileage column.

Mileage and Price Formatting Errors That Fail Posts: The Pattern Library

Train the floor on patterns, not on "be careful."

Price patterns

Rounding strategy is a different article. If you are choosing 9995 vs 10000, read rounding vehicle prices on Marketplace. This article is only about whether the field is a clean number at all.

Mileage patterns

Odometer replacements and exempt units are edge cases. They are not an excuse to type 0 or 1 to get the form to submit.

The silent cousins

• Description contradiction. Field says 42,000; paragraph says "under 40k." Pick the odometer.
• Stale miles on aged units. Format is right; the number is last month's. That will not always fail the post. It will fail the driveway.
• Price in title and field disagree. Title is marketing; the field is the number you will be held to.

A Validation Routine Before the Unit Hits the Queue

Do this at import and again at queue. Import catches file-level rot. Queue catches the one row a manager edited by hand.

Import gate

1. Open the file in a tool that shows raw values, not just pretty Excel.
2. Price column: digits only. No $, no commas, no .00 unless you have a documented cents convention and a conversion step.
3. Mileage column: digits only. No mi, no commas, no k.
4. Scan min/max. A $2,499,500 car in a lot of $12k–$40k cars is an extra zero. A 412-mile five-year-old SUV is missing digits or a comma that got eaten.
5. Fail the row. Do not "fix it in Marketplace."

Bulk CSV and Excel imports that log row-level errors exist so this gate is not a heroic spreadsheet session every Monday. If your process still pastes from email, you will keep seeing $.

Queue gate (thirty seconds)

• Read the price out loud against the desk or website.
• Read the miles against the odometer photo if you have one.
• If either field has a comma, a dollar sign, or a word, stop.

After a fail

If Marketplace rejected the post and the rest of the listing is fine, assume format first. Strip the field to integers, save inventory, retry once. If it still fails, you are not in a format problem anymore; go to the troubleshooting tree.

Edge Cases That Tempt People to Type Garbage

These are where honest managers create formatting errors on purpose.

Trade pending / appraised not reconditioned

You may not have a clean retail price yet. That is not a reason to post $1. Hold in draft.

Wholesale units on a retail account

If you are not ready to honor a retail number, do not invent a formatted placeholder. Off Marketplace until the desk has a real price.

BHPH packs

If the cash price and the "with financing" story differ, the Marketplace price field is still the cash number you will honor. Do not put a down payment in the price field. This is not legal advice; confirm advertising rules with counsel.

In-transit / no odometer photo yet

Blank is better than 1. Blank should fail import. That is the point. Get the miles or do not post.

Multi-location files

A file that mixes two stores sometimes mixes two currency formats or a column shift that dumps miles into price. The min/max scan exists for that.

Checklist before you call it "a Facebook glitch":

• Price is digits only, matches the desk
• Mileage is digits only, matches the cluster or jacket
• No $, k, mi, OBO in the numeric fields
• Min/max on the file is plausible for this lot
• Description does not contradict the fields
• Unit is actually for sale at that number today

How PostToMarket Automates This

Mileage and price formatting errors that fail posts survive when the only validation is a human staring at a Marketplace text box. By then the CSV has already won.

PostToMarket imports bulk CSV and Excel with import history and a row-level error log, so a blank price or a garbage mileage cell is a failed row at upload, not a failed Marketplace submit at 5 p.m. Inventory holds the numeric fields with the rest of the specs; AI-generated titles and descriptions are built from those specs, which makes a field-vs-copy contradiction easier to see before posting because you can edit the copy against the same record. Statuses (draft, posting, posted, sold, failed) keep a unit with bad numbers out of the "looks live" pile. Unlimited vehicles on every plan means you can leave a broken row in draft instead of forcing a placeholder through. The product does not invent a legal mileage for an exempt title and it does not guarantee Facebook will accept every submit. It keeps the integers in inventory where a manager can fix them once.

Clean Integers or It Does Not Leave Draft

Mileage and price formatting errors that fail posts are not a demand problem. A Tahoe that cannot post because of a comma is a file problem you can fix before the next aged-unit meeting.

PostToMarket is the workflow for that fix: import with error logs, inventory that stays in draft until the numbers are real, AI copy you edit, and paced posting once the row is clean. One-login lots run Starter at $59 per month. Teams that need up to 13 logins run Dealership at $299 per month.
