To bring spreadsheet citations into Zotero, first convert or export the records to a supported bibliographic format—such as RIS, BibTeX, or CSL JSON—then import that file through File → Import… → A file. Simply renaming a .csv file to .ris or .bib does not convert its contents.
Can Zotero import a CSV file directly?
CSV is not listed among Zotero’s documented import formats, and Zotero’s documentation does not provide a CSV column template or direct CSV import steps. Zotero does support a range of standardized bibliographic formats, including RIS, BibTeX, BibLaTeX, CSL JSON, and MODS. See Zotero’s import documentation for the current supported-format list and import workflow.

That distinction matters because a CSV is a table of values, not necessarily a bibliographic record file. Zotero needs records encoded in a format it recognizes; changing the filename extension alone leaves the CSV data unchanged.
Convert the CSV into a supported format
Start with the database or reference manager that produced the CSV
If the records came from a research database or another reference manager, return to that application and export the references as RIS, BibTeX, or CSL JSON if available. Zotero recommends using standardized formats such as RIS or BibTeX when transferring records from other programs. Choose an export that includes the fields you need, such as authors, title, date, DOI, and publication details; the available fields depend on the source application.
When choosing among formats, use one your source application exports reliably and that preserves the metadata needed for your project. Zotero describes RIS as convenient for quick edits and supports CSL JSON and BibTeX as well, but the documentation does not establish one format as universally best for every CSV conversion.
If the CSV is all you have
The spreadsheet must be converted into a valid bibliographic file before import. Zotero’s official guidance does not specify a universal CSV-to-RIS, CSV-to-BibTeX, or CSV-to-CSL-JSON recipe or field mapping. Check whether your spreadsheet or citation-management software offers bibliographic export, or use a conversion workflow that explicitly maps your CSV columns to the target format. Do not assume columns such as “Author” or “Year” will be interpreted correctly without checking the resulting records.
For a plain-text bibliography rather than structured CSV rows, Zotero’s help points to AnyStyle, which can parse many references into BibTeX or CSL JSON. That is a different workflow from converting a CSV, and Zotero advises checking the parsed results carefully for errors. See Zotero’s guidance on importing formatted bibliographies.

Import the converted file into Zotero
-
Save an untouched copy of the original CSV before converting it. Keep it as a fallback in case the conversion drops or alters fields.
-
Export or convert the records into a supported bibliographic format, such as RIS, BibTeX, or CSL JSON. Confirm that the output file contains formatted bibliographic records rather than comma-separated spreadsheet rows.
-
In Zotero, select File → Import… → A file.
-
Choose the converted file and follow the import prompts. Zotero’s documented file-import workflow applies to supported formats, not arbitrary CSV data.
-
Open a sample of the imported records and compare them with the source spreadsheet before using the batch. Check creator names, titles, dates, identifiers such as DOI, and item types. Correct conversion or field-mapping errors in the source or converted file as needed.

What to check when imported records look wrong
-
Authors appear in the wrong order or as one name: Check how the converter interpreted the author column, including whether it separated individual creators and distinguished given and family names.
-
Dates or identifiers are missing: Confirm those columns were included in the export and mapped to the corresponding bibliographic fields in the target format.
-
Records have the wrong item type: Check whether the source data or converter provided enough information to distinguish, for example, a journal article from a book or report.
-
The file will not import: Verify that it is actually encoded as the chosen supported format. An extension change does not repair CSV structure or create RIS, BibTeX, or CSL JSON records.

Bibliographic formats differ in how they represent fields and item types, so inspect representative records rather than assuming every field survived the conversion. Zotero discusses format compatibility and import/export limitations in its data-transfer guidance.

When import/export is the wrong way to move data
Importing a converted file is appropriate for bringing in a set of references. It is not Zotero’s recommended method for transferring an entire Zotero library: export/import can lose information, and links to Zotero items in existing word-processor documents are lost after export/import. For a full library move, use Zotero’s library-transfer guidance rather than treating the library as a CSV conversion. The limitations are described in Zotero’s transfer article.
Import from Clipboard is not CSV import
Zotero also documents Import from Clipboard for bibliographic data in a supported format such as RIS, BibTeX, or CSL JSON. It is not a way to paste arbitrary CSV rows and have Zotero map the columns. The import documentation covers supported import methods.
Browser-based import is a separate convenience
Zotero’s Connector may offer to import certain bibliography files opened in a browser, including RIS and BibTeX. That option can be useful when you already have a supported bibliography file; it does not convert a spreadsheet CSV. See Zotero Connector documentation.
