Source format: CSV
CSV stands for Comma-Separated Values. It is a plain-text format used to store tabular data, with each line representing a row and commas, semicolons, tabs, or other delimiters separating columns. CSV files are widely used by spreadsheets, databases, data analysis tools, and business applications because they are simple, compact, and easy to exchange between systems.
Typical CSV use cases include contact lists, product catalogs, data exports, and cleanup workflows. Because CSV is text-based, it can be opened in many editors and spreadsheet programs such as Microsoft Excel, LibreOffice Calc, and Google Sheets.
Target format: SAV
SAV is most commonly associated with IBM SPSS Statistics data files. It is a structured binary format designed for statistical analysis, storing not only values but also variable names, labels, value labels, missing-value definitions, and other metadata. This makes SAV especially useful for researchers, survey analysts, and organizations working with statistical datasets.
The main advantage of SAV over CSV is that it preserves richer data definitions for analysis in SPSS and compatible tools. It is commonly used in social sciences, market research, healthcare studies, and any workflow where metadata matters as much as the raw data.
How to convert csv to sav
The most reliable way to convert .csv to .sav is to import the CSV into IBM SPSS Statistics and then save the dataset in SPSS format. This is a conversion, not a simple rename, because the data must be parsed and typed correctly.
- Open IBM SPSS Statistics.
- Choose File → Open → Data.
- In the file type selector, choose CSV or Text, then select your
.csvfile. - Use the text import wizard to confirm the delimiter, decimal symbol, text qualifier, and whether the first row contains variable names.
- Check that each column is assigned the correct data type, especially numeric fields, dates, and categorical variables.
- After the data opens correctly, choose File → Save As.
- Select SPSS Statistics (*.sav) as the output format and save the file.
If you do not have SPSS, GNU PSPP is a free alternative that can open CSV data and save it as .sav in many cases. Another option is to use a compatible statistical package or a script-based workflow, such as R with packages that write SPSS files. For a quick browser-based option, you can also convert the file on 101convert.com for free, without installing any software.
Notes on quality, compatibility, and limitations
CSV to SAV is not a simple format rename; it is a data import that may change how values are interpreted. The most important issue is data typing: numbers, dates, and text must be recognized correctly during import, or SPSS may store them incorrectly.
CSV files do not contain metadata such as variable labels or value labels, so those details must be added manually after import if needed. Also, CSV delimiter conventions vary by region; some files use commas, others semicolons or tabs. Make sure the import wizard matches the file’s actual structure.
Compatibility can also depend on the SPSS version and the source data. Very large CSV files may take time to import, and malformed rows, embedded delimiters, or inconsistent quoting can cause parsing errors. For best results, clean the CSV first and verify the imported dataset before saving it as SAV.

Do I need to install any software to convert CSV to SAV?
No. The CSV to SAV conversion runs entirely online in your browser and works on Windows, Mac, Linux, Android and iPhone.
Did the conversion fail?
In most cases, the cause is an incorrect file format. Please upload a valid CSV file for this CSV to SAV conversion. Occasionally, the issue may be on our side. We analyze recurring conversion failures and disable or fix the converter if we detect a defect.
Will CSV column types and statistical metadata be preserved in SAV?
Basic values and column names can be transferred, but a CSV does not normally contain SPSS metadata such as variable labels, value labels, or defined missing values. These details must be inferred or added during conversion, so check the resulting variable definitions.
Why did my numbers or dates change after converting CSV to SAV?
The converter may infer whether each column is numeric, text, or a date from the CSV contents. Mixed values, ambiguous date formats, decimal separators, or blank cells can cause a column to be interpreted differently, so consistent formatting is important.
Will leading zeros and missing values be preserved in CSV to SAV conversion?
Leading zeros are preserved only when the column is treated as text; a value such as 00123 may become the number 123 if it is detected as numeric. Empty cells may become system-missing values, but CSV text such as NA or blank strings may need separate handling.
Why are some CSV rows or columns misread when converting to SAV?
Unescaped commas, quotation marks, line breaks inside fields, or inconsistent numbers of columns can make a CSV parser split records incorrectly. Correct CSV quoting and a consistent delimiter prevent rows from shifting or values from appearing in the wrong variables.
