Tabular
TabularSplit Large CSV into Multiple Files
Split a large CSV into smaller files by row count. Download all parts as a ZIP archive.
What this tool does
Many tools, APIs, and import wizards have row limits. Tabular splits your large CSV into evenly-sized chunks — for example, a 100,000-row file into 10 files of 10,000 rows each. All parts are bundled into a single ZIP download with the same headers in every file.
Problems it solves
- Splitting a large CSV for an import tool with a row limit
- Breaking up a batch file for parallel processing
- Dividing an export into manageable pieces for review
- Preparing chunks for an API that limits records per request
- Splitting a CSV before emailing or sharing with collaborators
Example
100,000-row file split into 10 files of 10,000 rows each.
Before
| data.csv |
| 100,000 rows |
After
| output_part01.csv — 10,000 rows |
| output_part02.csv — 10,000 rows |
| ... (10 files in a ZIP) |
Frequently asked questions
Are headers included in every output file?
Yes. Each chunk file contains the original header row followed by its slice of data rows.
What format are the output files?
All chunk files are CSV. They are bundled into a single ZIP archive for download.
Is this a Pro feature?
Yes. CSV file splitting is available on Pro and Business plans.
Is there a minimum rows-per-chunk value?
The minimum is 1 row per file, though values of 500–10,000 are most practical.
