CSV to QBO API: automate CSV to QuickBooks conversion. Send a CSV or Excel file, get a reconciled .qbo Web Connect file back, no browser, included on the Pro plan.
No account needed for your first conversions. We never store your bank login.
Short answer: Yes, there is a CSV to QBO API. On the Pro plan you send a CSV or Excel file to the conversion endpoint and receive a QuickBooks Web Connect (.qbo) file back, with no browser step. The same reconciliation the web tool runs, summing the parsed rows and matching them to the file total, runs on every API call, so automated output is held to the same accuracy as a manual conversion. Try one file free in the converter above, then wire the API into whatever produces your CSV files.
Last updated July 2026. If you are converting a handful of statements a month, the web tool is enough. The API is for the teams past that point: an accounting firm closing dozens of client files, a fintech that hands customers a downloadable .qbo, or an operations team that wants statements converted the moment they land in a shared drive. Instead of a person opening a browser, uploading a file, and downloading the result, the whole loop runs on its own.
The API accepts the same inputs as the tool (.csv, .txt, .xls, .xlsx, .xlsm), detects the date, description, and amount columns without a template, normalizes mixed date formats, strips currency symbols and thousands separators, and returns a real .qbo Web Connect file that QuickBooks Online and QuickBooks Desktop both import. You can also request XLSX or CSV output from the same call when you want a spreadsheet copy alongside the .qbo.
| Approach | Human step per file | Volume | Reconciliation check | Best for |
|---|---|---|---|---|
| CSV to QBO API (Pro plan) | None, fully programmatic | Unlimited | Runs on every call | Firms, fintech, automated pipelines |
| Batch upload in the browser (Plus plan) | Upload the batch, download the set | Hundreds a month | Runs on every file | Catch-up and cleanup work |
| Single file in the web tool | Upload and download one file | A few at a time | Runs on every file | Occasional conversions |
| QuickBooks native CSV upload | Map columns each time, one account | 1,000 rows / 350 KB per file | None | One-off manual imports |
Built for the CSV and Excel exports US banks and cards actually send, checked before it exports.
The converter adds up the transactions it parsed and matches that to your file total before you export, so nothing is silently dropped.
Valid OFX 1.02 with QuickBooks Web Connect headers. Online and Desktop import it as a standard bank feed.
Date, description, and amount are detected for you, so you skip QuickBooks' strict 3-column and 4-column CSV layout.
Bulk upload for catch-up and cleanup work. Each file gets its own reconciliation check and its own exports.
Mixed date formats, currency symbols, and stray commas that break a raw CSV import are cleaned up before the .qbo is built.
One conversion, three files: the .qbo for QuickBooks, an XLSX to review, and a CSV for everything else.
Three steps. No column-mapping wizard.
Drag in a CSV, XLS, or XLSX export from your bank, credit card, or accounting tool. Any column order is fine.
Every transaction is parsed and checked against your file total. You see the rows before exporting.
Download the .qbo and import it as a Web Connect bank feed. Excel and CSV are in the same download.

Yes. The Pro plan includes API access to the same conversion engine as the web tool. You send a CSV or Excel file to the endpoint with your API key and receive a .qbo Web Connect file in the response. There is no separate model to learn: anything the browser converter accepts, the API accepts, and the output is the identical reconciled .qbo QuickBooks reads.
Point your workflow at the API. When a bank or card CSV lands in a shared folder, a client portal, or your app, post it to the conversion endpoint and store the .qbo that comes back. Firms commonly wire it to a watched drive so client statements convert on arrival; developers embed it so their users get a QuickBooks-ready file without leaving the product. No one opens a browser, and the conversion runs the same reconciliation every time.
Yes. That is exactly what the API is for. You call it from any language that can make an HTTPS request with a file attachment, get back a .qbo, and hand that file to QuickBooks Online or Desktop. Because the engine detects columns on its own, you do not have to pre-format each CSV or maintain a mapping template per bank, which is what makes it safe to run unattended.
A real QuickBooks Web Connect (.qbo) file, the same format a bank issues, with a unique ID on each transaction so QuickBooks can block a double import. You can also request XLSX or CSV output from the same call. Every response includes the reconciliation result, so your pipeline can confirm the parsed total matched the source file before it moves the .qbo downstream.
API access is part of the Pro plan at $499 a month, or $249 a month billed yearly, which also includes unlimited conversions and team workspaces. The lower tiers cover the browser tool: Starter at $49 a month for 100 conversions, and Plus at $149 a month for 500 conversions with batch upload and duplicate detection. If your volume needs a custom arrangement, Enterprise is available through sales.
Yes. Because the Pro plan is unlimited, you can loop over a folder of statements and convert each one to its own .qbo in a single automated run, rather than uploading them by hand. Each file is reconciled individually against its own total, so a run of fifty statements is as trustworthy as one conversion, and a file that does not balance is flagged rather than shipped.
Yes, identically. The reconciliation is part of the conversion engine, not a feature of the browser interface, so an API conversion sums the parsed transactions and compares them to the file total exactly as a manual conversion does. That is the point of automating on a real engine rather than a script: the accuracy check does not get skipped just because no one is watching.
Start by converting one file in the tool above so you can see the .qbo the engine returns. To automate, use your Pro API key to post a CSV or Excel file to the conversion endpoint; the engine detects the columns, normalizes the dates, cleans the amounts, reconciles the total, and returns the .qbo. Store or forward that file to QuickBooks, and repeat for every statement your systems produce. The same call can hand back XLSX or CSV when you want a spreadsheet copy for your own records.
Accounting firms automate the conversion step of a multi-client close so staff spend their time categorizing, not reformatting spreadsheets. Fintech and lending products use it to give customers a QuickBooks-ready .qbo without building a converter in-house. Internal operations teams wire it into a document pipeline so bank and card exports become importable files the moment they arrive. All three want conversion that runs unattended and still reconciles every file.
Upload a CSV or Excel export, get a QuickBooks-ready .qbo back in seconds. No card to try it.
