    "content": "**Four columns have formally missing (NULL/blank) values, and a fifth, Amount in USD, has a large hidden gap.**\n\nFrom the null-rate query (step-0) and the blank-check query (step-1), out of 3,044 rows:\n\n- **Remarks**: 548 missing, 18.0%. This is the largest formal gap, and it is blank text rather than NULL.\n- **City  Location**: 6 missing, 0.2%.\n- **Investors Name**: 3 missing, 0.1%.\n- **InvestmentnType**: 3 missing, 0.1%.\n- **Complete columns (0% missing)**: Sr No, Date dd/mm/yyyy, Startup Name, Industry Vertical and SubVertical.\n\n**Caveats**\n- **Amount in USD** shows 0 NULLs, but step-1 found 966 blank values (about 31.7% of 3,044).\n- The value distribution (step-2) shows a literal text value 'N/A' in 959 rows (31.5%).\n- Together these suggest roughly a third of deals have no usable funding amount. The 966 blanks and the 959 'N/A' rows are counted separately, so I have not shown how they overlap. Treat Amount in USD as about 31–32% effectively missing.\n- Amount in USD is also stored as text with Indian-style comma grouping, for example '10,00,000'. It needs cleaning before numeric analysis.\n- A plain NULL count understates missingness here. The Remarks, City and Investors Name gaps appear as blank strings, not NULLs. Step-1 shows 0 NULLs in every column, and the blank counts match the step-0 missing counts (548, 6 and 3).\n- Industry Vertical and SubVertical show 0 blanks, but I did not check them for placeholder text like 'N/A'.\n- InvestmentnType shows 0 blanks in step-1, yet it is missing 3 in step-0. The step-1 output has no `blank_invtype` column, so that gap is likely NULL or blank text that step-1 did not report."
